There was a highly significant relationship between average PDSS and age (slope = 0.118 PDSS/month; 95 % CI: [0.096, 0.141], p < 0001); which remained true for both females (slope = 0.212 PDSS/year; 95 % CI: [0.181, 0.244], p < 0.001) and males (slope = 0.049; 95 % CI: [0.02, 0.078], p = 0.001), but the slope for rate in change in average PDSS/month was greater for females than for males (p < 0.001).
