Getting out of the House Study Statistical analysis plan

11. FINAL REPORT TABLES AND FIGURES COMMENT

Specify layout, for example by presenting dummy tables. The following rules may be adopted when creating the summary tables:

Number of decimal places (DP):

l for minimum and maximum the number of DPs will be the same as the raw data l for mean, median and SD the number of DPs will be one more than the raw data l percentages–Round up to the nearest whole number

l p-values–3 decimal points will be presented l no more than 4 significant numbers will be used.

Data presentation:

l Treatment group will be in columns with the visits in rows.

l Column headers in mixed case, with‘(n=nn)’below treatments to denote the denominator. l Decimal places will be aligned.

l n(%) as a separate column rather than included in brackets for each element of the table. l Categories (i.e. in column 1) in sentence case, in the order on the CRF.

l Ordering of statistics N, Missing, Mean, SD, CV%, Minimum, Median and Maximum. Geometric Means inserted between Mean and SD for pharmacokinetics.
