At > 18 months follow-up, three comparisons between the interventions and the active controls found a small and marginally significant pooled effect size ( g = − 0.24, 95% CI: − 0.48 to 0.01, p = 0.055, I 2 = 19.59), indicating less effectiveness of the interventions compared to the active controls in reducing depression symptoms.
