Egger’s test approached significance (P = 0.08), indicating possible small-study effects.
Publication bias assessment revealed slight funnel plot asymmetry and near-significant Egger’s test (P = 0.08), suggesting possible small-study effects favouring positive results.
While combined methods showed a trend toward improvement (RR = 1.06, 95% CI: 0.98–1.15), this did not reach statistical significance (P = 0.657), with no heterogeneity (I2 = 0%).
