Natural logarithmically transformed after the addition of 1 to each value.
BMI categories were defined as follows: Underweight: BMI < 20 kg/m2; Normal weight: 20 ≤ BMI < 25 kg/m2; Overweight: 25 ≤ BMI < 30 kg/m2; Obese class 1: 30 ≤ BMI < 35 kg/m2; Obese class 2+: BMI ≥ 35 kg/m2
The table includes all variables included in the multivariable adjusted analyses. Age was used as the time scale in these Cox regression analyses.
