Meta-analysis of the effects of ADSC intervention on TH+ neurons in the SN. The effect of ADSC intervention on dopaminergic neuron generation was reported in 7 individual experiments and 3 of them met the criteria for meta-analysis. The pooled effect size of SMD was 13.36 (95% CI 6.85 to 19.86, z-value = 4.02, P < 0.000 1)
