Relations of patient-reported outcomes to disease-related parameters of kidney-functioning.

*p-value is equal to or remains below the critical p-value after Bonferroni-Holm adjustment for multiple inferential tests (i.e. the number of subscales of the corresponding patient-reported outcome tool). Spearman rho correlation coefficients (p-values) are presented, including corresponding sample size for coefficient calculation. Values set in bold indicate p-values ≤ 0.05. For correlations of SF-12 and s-creatinine in the CKD/pre-KT subgroup without dialysis, we did not present results due to the sample size being below 5.
