  1. aHR adjusted hazard ratio, CI confidence interval, ESRD end-stage renal disease
  2. aHRs were adjusted for age, sex, and selected comorbidities (diabetes mellitus, stroke, anemia, heart failure, hypertension, hyperlipidemia, coronary artery disease, peripheral vascular disease, malignancy, depression, obstructive sleep apnea, insomnia, alcoholism, traumatic brain injury, Parkinson’s disease, myocardial infarction, atrial fibrillation, hyperthyroidism, and hypothyroidism)
