ITSN1 and androgen insensitivity syndrome: According to the median value of lnc‐ITSN1‐2 expression in AIS patients, the patients were further divided into two groups: the lnc‐ITSN1‐2 high‐expression group and the lnc‐ITSN1‐2 low‐expression group, and the Kaplan‐Meier curve was performed to investigate the correlation between lnc‐ITSN1‐2 expression and RFS in AIS patients, which presented that RFS was poorer in the lnc‐ITSN1‐2 high‐expression group compared with the lnc‐ITSN1‐2 low‐expression group (P = .007; Figure 3).
