The Study Characteristics dataset includes basic information about study design. In addition to study class, the dataset includes clinical setting, whether the study looked at PTSD symptom clusters, whether there were any subgroup analyses, type of diagnostic measure used (e.g., diagnostic interview, self-report), and provider credentials. Use this dataset to better understand the variety of RCT designs employed, compare studies by study class or to identify gaps in the literature for potential new RCTs. Visualizations made from this dataset will be based on the 389 RCTs included in the PTSD-Repository. Values reported as "NA" or not reported "NR" by the study are null values (empty cells). Data is at the study level.

The PTSD Outcomes Within Each Treatment Arm dataset includes information on how PTSD was measured and at which timepoint. Descriptive information is provided on which measure was used, the statistical approach to measuring change in PTSD, how PTSD was defined and the definitions of loss of diagnosis and clinically meaningful change, if these variables were included in the study.

Results in this dataset are provided for each treatment arm, and do not include comparisons across the arms (which can be found in the PTSD Outcome Comparisons Between Treatment Arms dataset described below). PTSD baseline mean score and standard deviation are provided as well as the within-treatment change from baseline. Within-group effect size is also included. The percent of participants who achieve loss of PTSD diagnosis and the percent who achieve clinically meaningful response are included for studies that reported these outcomes.
Use this dataset to learn about changes in PTSD within a specific treatment. For example, what is the change in Clinician Administered PTSD Scale score across all study arms of a specific treatment type? From the visualization, you can filter by PTSD measure of interest and type of treatment.

Values abstracted as not applicable ("NA") or not reported ("NR") by the study are null values (empty cells).

The Sample Characteristics dataset includes information on the participants who are included in the studies. This information is provided at the study level—meaning, data are not broken down into the specific treatment arms such as the intervention or control groups. Use this dataset if you want to learn more about the number of participants in the study; inclusion and exclusion criteria related to substance use and suicidality; baseline clinical characteristics such as PTSD severity, trauma type, military status, and comorbidities; and, basic demographic information such as age, gender or race for the sample as a whole (not individual participants). Visualizations made from this dataset will be based on the 389 RCTs included in the PTSD-Repository. Values reported as "NA" or not reported "NR" by the study are null values (empty cells). Data is at the study level.
