  1. Data are expressed as odds ratio, 95% confidence interval and p-value. The univariate logistic regression analyses was performed on 11 variables as potential predictors of adhering to dietary guidelines. The multivariate analysis was performed on four variables. Bold values indicate statistical significance.
  2. OR odds ratio, CKD-EPI Chronic Kidney Disease Epidemiology Collaboration, eGFR estimated glomerular filtration rate estimated using the CKD-EPI equation.
