FOXP3 and vitiligo: To study the impact of microRNA-based treatment, narrow band–UVB phototherapy, and Treg-associated treatments on Tregs' frequency, FOXP3, and IL-10 levels in vitiligo, we assessed the Tregs' frequency, FOXP3, and IL-10 levels in vitiligo patients and mouse model of vitiligo, pre- and posttreatment by calculating the standardized mean difference through meta-analysis.
