MKI67 and androgen insensitivity syndrome: By a one-way ANOVA, Tamhane's T2 test (with a Levene test for uneven variance between groups) compared the expression levels of Ki-67, and it was found that there was no significant difference between the AAH group and AIS group (p = 0.608), the AAH group and MIA group (p = 0.347), and the AIS group and MIA group (p = 0.159), but the AAH group (p <0.001), AIS group (P <0.001), and MIA group (p <0.001) were significantly different from the IAC group.
