Fig. 9. Late pain (24 h) at movement funnel plots assessing publication bias. Plotted is the SE versus  standard difference in mean (Effects). Vertical line  is the combined effect for early pain, with diagonal lines  representing the expected 95% CI from the combined effect. Studies outside the funnel indicate heterogeneity. (A ) Funnel plot for dexamethasone less than 0.1 mg/kg. There was no evidence of asymmetry on the funnel plot (P = 0.43, one-sided). (B ) Funnel plot for intermediate dose dexamethasone (0.11–0.2 mg/kg) and late pain with movement. Eggers regression demonstrated some asymmetry (P = 0.05, one-sided) with one study lying outside of the 95% CI. (C ) Funnel plot for high-dose dexamethasone (more than 0.2 mg/kg) and late pain with movement. Eggers regression demonstrated asymmetry (P = 0.01, one sided) with one study lying outside of the 95% CI.
