Quality of life data of control subjects and CKD patients, the latter also split into patients not requiring and requiring hemodialysis.

Data are means ± SD for normally distributed data or median (Q1;Q3) for non-normally distributed data. Data were evaluated by unpaired two-tailed t-tests for comparisons between control patients and all CKD patients. Data were evaluated by oneway ANOVA followed by Bonferroni or Games-Howell (non-equal variances) tests (normally distributed data) or Kruskall-Wallis followed by Mann-Whitney tests (non-normally distributed data) for comparisons between control subjects, CKD patients requiring hemodialysis and CKD patients not requiring hemodialysis.
