Funnel plot for the effect size of ADSC therapy. a Effect size of ADSC therapy on rotation behavior. b Effect size of ADSC therapy on rotarod test result. c Effect size of ADSC therapy on the number of TH-positive neurons. Dots represent individual studies. The solid vertical line represents the pooled effect size. The dashed diagonal lines represent pseudo-95% confidence limits around the pooled effect size for each standard error on the vertical axis. The diagonal solid line represents the fitted line between the treatment effect and its standard error for each study using Egger’s test
