Grading of Recommendations, Assessment, Development and Evaluation (GRADE) evidence profile of in-person versus therapist-guided remote cognitive behavioural therapy (CBT) on primary outcomes reported in randomized controlled trials (RCTs) involving patients with psychological and somatic complaints

  • Note: CI = confidence interval, IQR = interquartile range, SMD = standardized mean difference.

  • * All RCTs administered the same intervention in both treatment arms (CBT); however, patients and health care providers were unblinded to the method of delivery (remote or in-person CBT).

  • Although the I2 value showed moderate heterogeneity, we did not rate down the certainty of evidence because the magnitude and direction of effects were largely consistent across trials, and a substantial proportion of between-study variability was contributed by 1 trial (56) that contributed less than 2% of the weight to our pooled estimate.

  • A contoured-enhanced funnel plot showed no evidence of small study effects (Appendix 1, eFigure 3), and Egger’s test was nonsignificant.
