  1. P* - statistical significance for differences between HD, PD, CKD, TE, and NK groups for quantitative variables - Kruskal Wallis rank ANOVA and Fisher’s exact test for qualitative variables;
  2. P** - statistical significance for differences between HD, PD CKD, and TE groups for quantitative variables -
  3. Kruskal Wallis ranks ANOVA or Fisher’s exact test for qualitative variables: DM—diabetic nephropathy; HT—hypertension; KZN—glomerulonephritis; ADPKD—autosomal dominantly inherited polycystic kidney disease
