- BMI body mass index
- aORs were estimated using a multiple logistic regression model, with the predictors listed in the first column of the table
- bAge was used as a nonlinear continuous predictor. It was evaluated at the first sextile (“young” — i.e., 51 years), median (“medium” — i.e., 62 years), and fifth sextile (“older” — i.e., 70 years)
- cBMI was used as a nonlinear continuous predictor. It was evaluated at the first sextile (“low” — i.e., 21.7 kg/m2), median (“medium” — i.e., 25.0 kg/m2), and fifth sextile (“high” — i.e., 30.1 kg/m2)
