Systematic review automation technologies

Systematic review automation technologies

We surveyed literature describing informatics systems that support or automate the processes of systematic review or each of the tasks of the systematic review. Several projects focus on automating, simplifying and/or streamlining specific tasks of the systematic review. Some tasks are already fully automated while others are still largely manual. In this review, we describe each task and the effect that its automation would have on the entire systematic review process, summarize the existing information system support for each task, and highlight where further research is needed for realizing automation for the task. Integration of the systems that automate systematic review tasks may lead to a revised systematic review workflow. We envisage the optimized workflow will lead to system in which each systematic review is described as a computer program that automatically retrieves relevant trials, appraises them, extracts and synthesizes data, evaluates the risk of bias, performs meta-analysis calculations, and produces a report in real time.

Tiotropium in asthma: a systematic review

Tiotropium in asthma: a systematic review

Abstracts of articles identified in the search were reviewed independently by two of the authors. Articles meeting pre- identified inclusion and exclusion criteria were selected for evaluation in this systematic review. Disagreements about inclusion of individual articles were resolved by consensus or review by a third author. Included in the systematic review were all randomized controlled trials that evaluated the efficacy of tiotropium in patients with asthma. The clinical trials had to be at least 4 weeks in duration and to provide adequate information on clinically appropriate end points in asthma care (eg, change in lung function, exacerbation rates, and/or ICS dosing). Excluded were unpublished and ongoing research, animal studies, reviews, case reports, case series, editorials, and studies in COPD patients (with or without asthma). The references of published articles identified in the search were examined for additional studies appropriate for inclusion in the review.

SYSTEMATIC REVIEW Chemoprevention of oral cancer in leukoplakia patients: A systematic review and meta-analysis

SYSTEMATIC REVIEW Chemoprevention of oral cancer in leukoplakia patients: A systematic review and meta-analysis

The systematic review and meta-analysis of published randomised controlled trials (RCTs) was conducted to review the effectiveness of current chemopreventive agents in the treatment of oral leukoplakia lesions (OPLs) and prevention of their progression to oral cancer. Material was identified through a retrospective literature search of the electronic PubMed database, Embase and Cochrane Library between 2008 and 2016.Eight RCTs were included for systematic review. The pooled estimate showed a 14% greater chance of responding for those randomised to interventions compared with placebo (Risk Ratio [RR] 1.14, 95% confidence interval [CI] 0.72 to 1.81). The CI from individual studies overlapped. The results suggested that there were no significant differences in comparing clinical responses between chemopreventive agents with placebo in treatment of OPLs. It is time to investigate new agents for oral cancer chemoprevention. Keywords: Chemopreventive, Clinical response, Oral cancer, Oral premalignant lesions.

Headache and pregnancy: a systematic review

Headache and pregnancy: a systematic review

This systematic review summarizes the existing data on headache and pregnancy with a scope on clinical headache phenotypes, treatment of headaches in pregnancy and effects of headache medications on the child during pregnancy and breastfeeding, headache related complications, and diagnostics of headache in pregnancy. Headache during pregnancy can be both primary and secondary, and in the last case can be a symptom of a life-threatening condition. The most common secondary headaches are stroke, cerebral venous thrombosis, subarachnoid hemorrhage, pituitary tumor, choriocarcinoma, eclampsia, preeclampsia, idiopathic intracranial hypertension, and reversible cerebral vasoconstriction syndrome. Migraine is a risk factor for pregnancy complications, particularly vascular events. Data regarding other primary headache conditions are still scarce. Early diagnostics of the disease manifested by headache is important for mother and fetus life. It is especially important to identify “ red flag symptoms ” suggesting that headache is a symptom of a serious disease. In order to exclude a secondary headache additional studies can be necessary: electroencephalography, ultrasound of the vessels of the head and neck, brain MRI and MR angiography with contrast ophthalmoscopy and lumbar puncture. During pregnancy and breastfeeding the preferred therapeutic strategy for the treatment of primary headaches should always be a non-pharmacological one. Treatment should not be postponed as an undermanaged headache can lead to stress, sleep deprivation, depression and poor nutritional intake that in turn can have negative consequences for both mother and baby. Therefore, if non-pharmacological interventions seem inadequate, a well-considered choice should be made concerning the use of medication, taking into account all the benefits and possible risks.

A systematic review on keystroke dynamics

A systematic review on keystroke dynamics

The application of the systematic review involves three major phases: planning, conduction and presentation of results. In the first phase, a review protocol is defined, in which research questions are specified along with search strategies. After that, in the second phase, the review pro- tocol is applied and the information is extracted from the returned references. References used for the extraction of information are called primary studies, while the review is a secondary study. Finally, the third phase defines the way to present the results and the final report is done. The items comprehended in each of the three phases are [33]:

Adherence influencing factors – a systematic review of systematic reviews

Adherence influencing factors – a systematic review of systematic reviews

Although the quality of systematic reviews was moder- ate to high, there is a loss of information in our overview because of poor reporting in the systematic reviews. Thus, we often had to rate the evidence for effect as unclear not because of a “real” lack of evidence. For example it was not possible to include the effect size and number of in- cluded patients in the evidence synthesis because with one exception [16] none of the studies provide information on these. It appears that some studies report only significant comparisons. These impression is also in accordance with prior research [24]. For such reviews that did not mention the total number of comparisons for a certain factor but only the statistical significant comparisons it is impos- sible to make a summary estimation of effect. Conse- quently the evidence for effect in the systematic review of Daley et al. and Verbrugghe et al. had to be judged as unclear, throughout [12,17].

A systematic review on business analytics

A systematic review on business analytics

We obtained academic literature from two databases: Web of Science and Scopus. These two databases are widely recognized and contain publications of high quality from peer-reviewed journals (Harzing & Alakangas, 2016). As a set of well-established selection criteria are the foundation of a rigorous systematic review, we set several rules for literature selection before screening publications in the database (Okoli, 2015). Firstly, the publications should contain business analytics in the title. Secondly, we only considered publications in English. Thirdly, regarding the publication type, we included articles and reviews. Furthermore, to include papers of high impact, we set a requirement on number of citations. For those papers published before 2017, we only considered those been cited more than five times, and for the papers published in 2017 and 2018, which usually have fewer citations due to the newness, we considered papers been cited at least once. By setting this threshold of citation number, we included the papers of high impact in the academia in this study. Finally, the core of the selection process, to ensure the relevance of the publications selected, searching business analytics in titles is not enough. And it is not feasible to read all the papers entirely even though the first four criteria would have narrowed the number of results. To deal with this, we read the abstracts to decide if the paper fits with the goal of the research. Additionally, the length of the paper should be long enough to cover adequate information, and the content of the paper should be relevant to business analytics.

The prevalence of stillbirths: a systematic review

The prevalence of stillbirths: a systematic review

Results: We identified 389 articles on stillbirth prevalence among the 2580 included in the systematic review. We included 70 providing 80 data sets from 50 countries in the meta-analysis. Pooled prevalence rates show variation across various subgroup categories. Rates per 100 births are higher in studies conducted in less developed country settings as compared to more developed (1.17 versus 0.50), of inadequate quality as compared to adequate (1.12 versus 0.66), using sub- national sample as compared to national (1.38 versus 0.68), reporting all stillbirths as compared to late stillbirths (0.95 versus 0.63), published in non-English as compared to English (0.91 versus 0.59) and as journal articles as compared to non-journal (1.37 versus 0.67). The results of the meta- regression show the significance of two predictor variables – development status of the setting and study quality – on stillbirth prevalence.

Science of floorball: a systematic review

Science of floorball: a systematic review

Results: Of 75 articles screened, 19 were included in this systematic review. One article each was identified in the fields of sports management and sports psychology, and the remaining 17 articles were in the field of sports medicine. Injury epidemiology in floorball players was the most thoroughly examined topic of research. To date, no research has been performed on the incidence of floorball-related injury, or any aspect of the sport, in children and adolescents. Conclusion: Collaborative research among sports science disciplines is needed to identify strategies to reduce the incidence of injury and enhance the performance of licensed floorball players. Despite the increasing popularity of floorball in recent years, surprisingly little research has examined this sport.

Systematic review and meta analysis

Systematic review and meta analysis

All coding of the intervention studies was carried out by the first author of the present paper. A sample of 4 of the 47 intervention studies which met the inclusion criteria (9%) was coded independently by two of the systematic review co-authors. The overall percentage agreement rate between the two independent coders was 89% (range 62.5%- 100% per item). The most common source of lack of agreement was omission by coders of minor details of a kind that would have been resolved by discussion (for example, calculation of standard deviations using the formula for populations rather than that for samples). A further confirmatory point-by-point check on a second sample of 5 papers (11% of the total number of included studies) yielded 99% agreement.

Childhood depression: a systematic review

Childhood depression: a systematic review

We performed a qualitative systematic review of articles about childhood depression published in previously chosen elec- tronic databases. The qualitative approach was chosen because quantitative methods, such as meta-analysis, show that: (a) the necessary information in order to calculate result size is not available, and may limit this analysis to a small subset of studies; (b) age intervals regarding childhood vary greatly among studies included in the sample, making it difficult to adequately compare and to do proper statistical analyses.

What is a systematic review?

What is a systematic review?

Reviews have always been a part of the healthcare literature. Experts in their field have sought to collate existing knowledge and publish summaries on specific topics. Traditional reviews may, for instance, be called literature reviews, narrative reviews, critical reviews or commentaries within the literature. Although often very useful background reading, they differ from a systematic review in that they are not led via a peer-reviewed protocol and so it is not often possible to replicate the findings. In addition, such attempts at synthesis have not always been as rigorous as might have been hoped. In the worst case, reviewers may not have begun with an open mind as to the likely recommendations, and they may then build a case in support of their personal beliefs, selectively citing appropriate studies along the way. Indeed, those involved in developing a review may well have started a review (or have been commissioned to write one) precisely because of their accumulated experience and professional opinions. Even if the reviewer does begin with an open mind, traditional reviews are rarely explicit about how studies are selected, assessed and integrated. Thus, the reader is generally unable to assess the

Systematic review of systematic reviews for medical cannabinoids

Systematic review of systematic reviews for medical cannabinoids

Data extraction. Paired, independent data extraction (G.M.A. with C.R.F., D.P., J.R., or J.T.) was performed, with disagreement resolved by consensus. Data were extracted on number of RCTs, number of patients, spe- cific focus (eg, neuropathic pain), baseline character- istics (average age or sex proportion), cannabinoid intervention (types and doses), control intervention (pla- cebo or specific active control), risk-of-bias tool used to assess RCTs, risk of bias found, other quality issues, and findings (benefits and harms). When considering the number of RCTs in a given systematic review, only those focused on pain, spasticity, nausea and vomit- ing, or adverse events were considered. The total num- ber of patients reported for each systematic review was, whenever possible, the summed number of patients ran- domized in (not those completing) all included rele- vant RCTs. If the number of RCTs or patients was not reported for adverse events, we reported the number of RCTs and patients included in the largest meta-analysis of adverse events for that systematic review.

Systematic review or scoping review? Guidance for authors when choosing between a systematic or scoping review approach

Systematic review or scoping review? Guidance for authors when choosing between a systematic or scoping review approach

Systematic reviews can be broadly defined as a type of research synthesis that are conducted by review groups with specialized skills, who set out to identify and re- trieve international evidence that is relevant to a particu- lar question or questions and to appraise and synthesize the results of this search to inform practice, policy and in some cases, further research [11–13]. According to the Cochrane handbook, a systematic review ‘uses expli- cit, systematic methods that are selected with a view to minimizing bias, thus providing more reliable findings from which conclusions can be drawn and decisions made.’ [14] Systematic reviews follow a structured and pre-defined process that requires rigorous methods to ensure that the results are both reliable and meaningful to end users. These reviews may be considered the pillar of evidence-based healthcare [15] and are widely used to inform the development of trustworthy clinical guide- lines [11, 16, 17].

Automating data extraction in systematic reviews: a systematic review

Automating data extraction in systematic reviews: a systematic review

“On demand” access to summarized evidence and best practices has been considered a sound strategy to satisfy clinicians’ information needs and enhance decision- making [57–65]. A systematic review of 26 studies con- cluded that information-retrieval technology produces positive impact on physicians in terms of decision en- hancement, learning, recall, reassurance, and confirmation [62]. Slaughter et al. [45] discussed necessary next steps towards developing “living systematic reviews” rather than a static publication, where the systematic reviews can be continuously updated with the latest knowledge available. The authors mention the need for development of new tools for reporting on and searching for structured data from published literature. Automated information extrac- tion framework that extract data elements have the poten- tial to assist the systematic reviewers and to eventually automate the screening and data extraction steps.
