Notes: ACR is log adjusted, inverse-logarithm was used when interpreting the estimates. Parameters were estimated using mixed-effect model to account for the within-subject correlation due to repeated measures.

Abbreviations: ACR, albumin (mg)-to-creatinine (g) ratio; CKD, chronic kidney disease; DBP, diastolic blood pressure; F&V, fruit and vegetable.
