  1. aModel 1: Unadjusted.
  2. bModel 2: Adjusted for age, gender, body mass index, heart rate, diabetes, cardiovascular disease, PD vintage, mean arterial pressure, and residual urine volume.
  3. cModel 3: Model 2 + adjusted for high sensitivity C-reactive protein, serum albumin, total cholesterol, and intact parathyroid hormone.
  4. dDid not adjust gender while analyzing sex × skeletal muscle mass, male or female PD patients.
