Further, none of positive results of sensitivity analysis were considered noteworthy (FPRP >0.2).These positive findings should be interpreted with caution and indicate that an increased breast cancer risk may most likely result from false-positive results, rather than from true associations or biological factors on the combined effects of GSTM1 and GSTT1.

Thus, logistic regression analysis adjusted by tumor size revealed a positive association between GSTT1 deletion and recurrence risk in general BC (OR 4.25; p = 0.04), while GSTM1 was negatively associated with recurrence risk in ER/PR<sup>+</sup>HER2<sup>-</sup> samples (OR 0.07; p = 0.03).
