KLK3 and posterior cortical atrophy: After comparing the ROC curve of the lncRNA assay with those of the base model, PSA and f/t PSA, it was determined that the AUC value of the lncRNA assay was much higher than those of the PSA (p < 0.001), f/tPSA (p < 0.001) and the base model (p = 0.001) for distinguishing PCa from patients with a negative biopsy (Figure 2d and Table 2).
