Analysis of metabolic profiling in effective vitiligo self-control group. (a) Relative intensity of differential metabolites at different visits. (MetaboAnalyst 3.0, https://www.metaboanalyst.ca) (b) Sixteen of the metabolites showed a gradually increasing or decreasing trend with the improvement of the disease, with 8 gradually elevating and 8 gradually decreasing. (R package of pheatmap, R.3.4.2) (c–e) A panel consisting of 4-Methoxy-17beta-estradiol, dehydroepiandrosterone and cortexolone was used for predictive model construction using logistic regression. The ROCs were analyzed between baseline and first follow-up samples (c), baseline and second follow-up samples (d), baseline and third follow-up samples (e).
