Fig. 4

Funnel plot of standard mean difference (SMD) versus standard error (SE). The SMDs of the pain score are plotted on the x-axis, and the standard error of the SMD is plotted on the y-axis. The vertical dotted line indicates the mean value of the SMDs. Visual inspection of the funnel plot of the SMDs of the pain score did not reveal substantial asymmetry. Egger’s linear regression test indicated no evidence of reporting bias among the studies (t = − 2.03; P = 0.06)
