Linear Regression of ΔHSDS at Year 1 and Year 2 on Baseline Age. At both (A) Year 1 (n = 76; correlation = -.3156; P = 0.0055) and (B) Year 2 (n = 49; correlation = -.3394; P = 0.017), there was a significant negative correlation between ΔHSDS and baseline age (ie, ΔHSDS decreased as baseline age increased).
