To verify the progression-free interval (PFI) evaluation of gene status in the context of androgen deprivation therapy (ADT) for PCa patients, we performed a multivariable Cox regression analysis to fit the four genes (SCD, NARS2, ALDH1A1, and NFXL1) into an initial model. The gene discussed is NFXL1; the disease is posterior cortical atrophy.
