Table 3: Logistic regression analysis of variables predicting prostate cancer. Differentially expressed between PCa and BPH group (KLK3, KLK11, miR-9-3p and miR-19a-3p) were included. Prediction models are based on mRNA expression of each gene. |β|, absolute value of regression coefficient; OR, odds ratio; CI, confidence interval; AUC, Area Under Curve.
