COX7A2L and breast carcinoma: In a clinicopathological study evaluating the association between COX7RP immunoreactivity and various variables in 168 breast carcinomas, COX7RP immunoreactivity was significantly associated with lymph node status (P = 0.003, χ2 test), ERα status (P = 0.01, χ2 test), or ERα-labeling index (P = 0.0004, χ2test) (Supplementary Table 1).
