  1. Multivariate-adjusted geometric means (95% CIs) (Model 1) of the UNa/K ratio were calculated by analysis of covariance with adjustment for age, sex, body mass index, current smoking, current drinking and regular exercise, living alone or not, and having a decreased income or not
  2. Multivariate-adjusted geometric means (95% CIs) (Model 2) of the UNa/K ratio were calculated by analysis of covariance with adjustment for age, sex, body mass index, current smoking, current drinking and regular exercise, living alone or not, having a decreased income or not, and residential state
  3. Multivariate-adjusted geometric means (95% CIs) (Model 3) of the UNa/K ratio were calculated by analysis of covariance with adjustment for age, sex, body mass index, systolic blood pressure, estimated glomerular filtration rate, hemoglobin A1c and low-density lipoprotein cholesterol levels, K6 score, current smoking, current drinking and regular exercise, living alone or not, and having a decreased income or not
  4. Multiple comparisons adjusted by Bonferroni correction were performed
  5. UNa/K ratio urine sodium-to-potassium ratio, TC total collapse, HC half collapse, PC partial collapse, ND no damage, CI confidence interval
