The data indicated that the high Lp(a) level was still independently correlated with the presence of high-risk PCa after adjusting for confounders including age, BMI, hypertension, diabetes, CAD, and lipid-lowering drugs in multivariate logistic regression analysis (Q4 vs. Q1, OR = 2.890, 95% CI: 1.148–7.274, p = 0.024) (Table 4). Here, LPA is linked to diabetes mellitus.
