Multivariable-adjusted associations between natural log-transformed fibroblast growth factor-23 and anthropometrics (BMI and WC, waist circumference) in the overall sample and by chronic kidney disease (CKD) status.

Model 1 is adjusted for age, sex, race, and region of residence. Model 2 is adjusted for indices of socioeconomic status, history of coronary heart disease and/or stroke, lifestyle habits (tobacco usage, alcohol consumption, physical activity), serum calcium, phosphorus, eGFR and UACR. In models stratified by CKD status, Model 2 was not adjusted for eGFR and UACR.
