Table values were computed using the derivation data. The odds ratios for the following predictor variables are presented for a 1‐SD higher level of the exposure value: age, neck circumference, waist circumference, height, high‐density lipoprotein cholesterol, clinic SBP, and clinic DBP. ACR indicates albumin/creatinine ratio; DBP, diastolic blood pressure; HDL, high‐density lipoprotein; SBP, systolic blood pressure; ···, a variable was not selected for inclusion in the corresponding equation.
a
This is a nonlinear variable in the predictive equation. The odds ratio is presented using the mean as a reference value.
