¹Multivariate model 1 was adjusted for current smoking status, and alcohol consumption;

²Multivariate model 2 was adjusted for subcutaneous adipose tissue (SAT) and visceral adipose tissue (VAT), in addition. Since body mass index (BMI) showed co-linearity to adipose tissue amount, it was not included in the analysis;

³P value for test of trend of odds.
