AR and posterior cortical atrophy: AR protein expression in the ADT-PCa group was increased by 80% compared with that in the primary PCa group (p < 0.01), showing an increasing trend in the ADT ≤12 months subgroup compared with the PCa group (p = 0.2), and AR protein expression was significantly higher in the ADT > 12 months subgroup (100; p < 0.01) (Table 3).
