This dataset provides results for between-arm comparisons of continuous measures. Included is information on score differences, p-value for statistical test, and study-reported effect sizes.

Where possible, the between-arm standardized effect size was calculated, using Hedges’ g. We calculated Hedges’ g based on the following (in order of preference): 1) adjusted mean difference; 2) follow-up scores; 3) unadjusted mean difference; 4) change scores. For the calculated effect size, information on the basis for calculation is included along with measures of variance. Negative values for Hedges’ g indicate a larger decrease (or lower follow-up score) in the first arm than in the second arm, while positive values indicate the reverse.

Each comparison is on a separate row, and pairwise as well as omnibus (multi-arm) comparisons are included. There are also separate rows for each measure, time point and analysis type.

Identifying information about each study, including citation, PubMed ID, PTSDPubs ID, ClinicalTrials.gov ID, and funding source(s).

Records references to secondary studies and companion publications included with primary studies in the PTSD-Repository.
These secondary, referenced studies may or may not have contributed data to the abstraction of the listed primary study. The relationship of the secondary study to the primary study is described in some cases in the `Secondary Study Relationship` column.
