Table 2.
4-bin scoring of androgen receptor (AR) positivity in young (2 months, n = 8) and aged (24 months, n = 9) prostates. Values are percentages (%) of AR-negative (0) and mild- (1), moderate- (2), and strong- (3) AR-positive cells. Values are presented as mean (SD). Bold values have statistical significance in young vs. aged by Student’s t-test (equal variances)/Welch’s t-test (unequal variances). *p < 0.05, **p < 0.01, ***p < 0.001.
