aIn the population column, male alone or female alone denotes that at least 80% of the study population was male or female. If only one trauma type is listed, at least 80% of the study population reported that type of trauma.

bPTSD outcome measure change data were obtained either directly from the study, when provided, or by subtracting data reported at treatment completion (not follow-up data) from baseline data (before treatment began). Average baseline score when reported or when baseline scores for all arms are nearly the same; otherwise, baseline scores listed individually in order of arm.

cThis study did not have a typical endpoint, because the treatment was a single session, and the “endpoint” was the 6-week post-treatment assessment.

dPre-Tx scores for dropouts.

eImmediate vs. delayed E+CR groups; 2nd group served as control, then began Tx after group 1 completed 12 sessions.

fI = immediate; D = delayed.
