Other therapies compared with Waitlist/Usual Care for chronic post‐traumatic stress disorder (PTSD) in adults
Patient or population: Adults with PTSD for at least 3 months Settings: Primary care, community, outpatient Intervention: Other therapies Comparison: Waitlist/Usual Care
Outcomes	Illustrative comparative risks* (95% CI)		Relative effect (95% CI)	No of Participants (studies)	Quality of the evidence (GRADE)	Comments

Severity of PTSD symptoms ‐ Clinician		The mean severity of PTSD symptoms ‐ clinician in the intervention groups was 0.58 standard deviations lower (0.96 to 0.20 lower)		112 (3 studies)	⊕⊝⊝⊝ very low1

*The basis for the assumed risk (e.g. the median control group risk across studies) is provided in footnotes. The corresponding risk (and its 95% confidence interval) is based on the assumed risk in the comparison group and the relative effect of the intervention (and its 95% CI). CI: Confidence interval; RR: Risk ratio;
GRADE Working Group grades of evidence High quality: Further research is very unlikely to change our confidence in the estimate of effect. Moderate quality: Further research is likely to have an important impact on our confidence in the estimate of effect and may change the estimate. Low quality: Further research is very likely to have an important impact on our confidence in the estimate of effect and is likely to change the estimate. Very low quality: We are very uncertain about the estimate.

¹Small sample sizes
 ²Studies were judged to pose a low/unclear risk of bias
