KLK3 and adenocarcinoma: Additional analysis in patients with adenocarcinoma revealed that PSA levels were positively correlated with Gleason score (Pearson r = 0.7865; p < 0.0001; Supplementary Table 1), and FLNA levels were negatively correlated with Gleason score (Pearson r = -0.3921; p < 0.05; Supplementary Table 1).
