HR hazard ratio, 95% CI 95% confidence interval, VAT visceral adipose tissue, SAT subcutaneous adipose tissue, TAT total adipose tissue
^aAdjustment was made for age, sex, smoking status, hypertension, and diabetes
^bAfter excluding 1 case with no available data on body mass index, HR was estimated using the remaining 52 cases
