Pairwise meta-analysis used mean differences (MDs), and network meta-analyses evaluated exercise-type and weekly-volume nodes. The review was registered in PROSPERO (CRD420251275738).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Twenty-four randomized controlled trials involving 1, 792 unique participants (912 intervention and 880 control) were included. Exercise was associated with lower EPDS scores than usual care\/non-exercise control (MD = -2.73, 95% confidence interval (CI) -3.57 to -1.88; I\n                      <jats:sup>2<\/jats:sup>\n                      = 95%), representing an average effect across highly heterogeneous studies. Delivery format showed no difference in an omnibus comparison across three reported categories (p = 0.29), and intervention composition also showed no subgroup difference (p = 0.66). Interventions lasting &amp;lt;12 weeks showed a larger pooled effect than those lasting \u226512 weeks (subgroup p = 0.009), but this was exploratory. In the exercise-type network, yoga\/mind-body exercise ranked highest (surface under the cumulative ranking curve (SUCRA) = 94.2%) and was estimated to lower EPDS scores versus aerobic exercise (MD = -2.62, 95% CI -5.16 to -0.08); active-vs-active estimates were entirely indirect and network certainty was very low. The 45\u201390 min\/week category ranked highest in the weekly-volume network (SUCRA = 84.6%), but no between-volume contrast was statistically significant.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Exercise may reduce postpartum depressive symptom scores, but mixed prevention-oriented and treatment-oriented samples, substantial heterogeneity, co-interventions, and star-shaped networks preclude identifying an optimal exercise type or dose.
