Leptin concentration was negatively correlated with the adiponectin/leptin ratio (rs = −0.787, p < 0.001) as well as the number of years after breast cancer diagnosis (rs = 0.510, p = 0.018), and it was positively correlated with BMI (rs = 0.430, p = 0.050). Here, ADIPOQ is linked to breast carcinoma.
