KDM6B and posterior cortical atrophy: In addition, KDM6B expression in the low PSA group (<20) is higher than that in the high PSA group (≥20), which causes us to wonder whether there is a negative correlation between ARs and KDM6B. Furthermore, a univariate and multivariate survival analysis showed that overexpressed KDM6B was correlated with the early recurrence of PCa, but no correlation was found between KDM6B expression and overall survival.
