aRRR: Relative risk ratio.
Linearity of age and waist circumference were checked and reported to be linear.
No interaction was found.
Overall fitness reported to be Hosmer-Lemeshow test (logit function 1, p = 0.897; logit function 2: p = 0.134); overall correctly classified percentage ((logit function 1, 88.0%; logit function 2: 82.6%); area under the ROC curve (logit function 1, 75.8%; logit function 2: 79.9%).
Regression diagnostic for individual fitness was performed, and no removal of individual case.
The percent changes in regression coefficient less than 20%.
