aAll P values were greater than 0.05 using a logistic regression both when unadjusted and when adjusted for age, body mass index, and gender. bEight subjects from the control group and four subjects from the incidence group did not have whole-organ magnetic resonance imaging score (WORMS) readings available. Various subjects had lesions in multiple compartments. |
