Summary of findings 6. EMDR compared with non‐TFCBT for chronic post‐traumatic stress disorder (PTSD) in adults.

EMDR compared with non‐TFCBT 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: Eye movement desensitization and reprocessing (EMDR) Comparison: non‐trauma‐focused CBT
Outcomes	Illustrative comparative risks* (95% CI)		Relative effect (95% CI)	No of Participants (studies)	Quality of the evidence (GRADE)	Comments
	Assumed risk	Corresponding risk

Severity of PTSD symptoms ‐ Clinician‐rated		The mean severity of PTSD symptoms ‐ clinician in the intervention groups was	0.35 standard deviations lower (0.90 lower to 0.19 higher)	53 (2 studies)	⊕⊝⊝⊝ very low1,2

*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.

¹Studies reported insufficient information to judge risk of bias
 ²Small sample sizes. Only two studies.
