Begg’s funnel plot. (a) Sensorimotor function. (b) Neurological motor function. There was evidence of small study effects (Egger’s test bias coefficient: −4.9792, 95% confidence interval (CI): −6.729 to −3.229, P <0.0001; and 5.6357, 95% CI: 3.6827 to 7.5886, P <0.0001). s.e., standard error; SMD, standardized mean difference.
