Note. Total N = 1,228; PTSD = posttraumatic stress disorder; RCT = randomized controlled trial; UCT = uncontrolled trial; CCT = comparative clinical trial; Quasi = quasi-randomized controlled trial; M = mean; % = percentage; Dx = PTSD diagnosis at posttreatment; SAM= statistical analysis method; ITT = intent to treat; CA = completer; PE = prolonged exposure; CPT = cognitive processing therapy; CT = cognitive therapy; EMDR = eye movement desensitization reprocessing; CAPS = Clinician Administered PTSD Scale; IES(-R) = Impact of Events Scale (-Revised); MS (-Com or -Civ) = Mississippi Scale for PTSD (-Combat or -Civilian); PCL (-S or -M) = Posttraumatic Stress Disorder Checklist (-Specific or -Military); PSS (-SR) = Posttraumatic Stress Scale Interview (-Self Report); PTSD-I = PTSD Interview; SIP (-I or -SR) = Structured Interview for PTSD (-Interview or -Self Report); NR = not reported.

a

The study sample was excluded from trauma type analysis because trauma type was not indicated and author did not respond through correspondence.

b

The study sample included some participants with non-combat traumas, but only the participants with combat trauma were included in the trauma type analysis due to small n in other trauma type categories (Rauch et al., 2009: n = 8; Thorp et al., 2012: n = 5);

c

The study sample was separated by trauma type in analysis for reasons described in the Methods section; studies with a trauma type category defined as “Mixed” without a superscript were not separated by trauma type in trauma type analysis.

d

Denotes the study sample was separated by population type for population analysis.

*

study was identified as an outlier based on SAM-D statistic.
