Potential bias
Sixty-three percent of studies scored three points while thirty-one percent scored two out of five on the Jadad Scale. One study (6%) scored one out of five. Fifty-six percent of studies provided evidence of allocation concealment (see Online Supplement Figure 1 for study quality and allocation concealment based on the Jadad Scale).
Synthesis of data
Main Effect- Continuous Outcome
Across all trials reporting depressive symptoms as a continuous outcome there were no significant differences at baseline (see Online Supplement Figure 2). In this population, post-intervention depressive symptoms were lower in the exercise compared to the control group (n= 1,327; SMD= -0.34, 95% Confidence Interval [95% CI]= -0.50, -0.19, I2= 37%; see Online Supplement Figure 3). Analysis including only the 14 trials that used EPDS as an outcome measure demonstrated a decrease in EDPS scores (WMD= -1.92, 95% CI= -2.91, -0.92, I2= 55%; see Online Supplement Figure 4).
Women with Depression vs. General Postpartum Population
In the sub-group analysis comparing women with depression and the general postpartum population, exercise was found to be beneficial in reducing depressive symptoms in both groups: women with depression (SMD= -0.48, 95% CI= -0.73, -0.22, I2= 42%) and general postpartum (SMD= -0.22, 95% CI= -0.36, -0.08, I2= 2%; see Figure 2). Analysis of the 14 trials using EPDS showed a post-intervention WMD of -2.57 (95% CI= -4.15, -1.00, I2= 63%) in the subgroup including…
