FOXP3 and breast carcinoma: As shown in Supplementary Fig. 4b, high FOXP3 expression was a protective factor for breast cancer survival (HR = 0.77, log-rank P < 0.001), while high VEGF expression was a deleterious factor for breast cancer survival (HR = 1.34, log-rank P < 0.001) (Supplementary Fig. 4c).
