Comparisons of EQ-5D-Y and PedsQL in pediatric patients with mild-to-moderate chronic kidney disease in longitudinal analyses

Table 3 Correlations between the changes of EQ-5D-Y and PedsQL scores across times among who completed both initial and latest follow-up assessments (n = 83)

	Absolute difference in summary scores of EQ-5D-Y				Change in each dimension of EQ-5D-Y
Difference in PedsQL	VAS		LSS		Mobility		Usual activities		Pain/ discomfort		Anxiety/ depression

“Self-care” of EQ-5D-Y is not presented due to the no patients reported any problems at initial (T1) and the latest follow-up assessments (T2)
Difference = T2 score minus T1 score; 3-level change in each dimension of EQ-5D-Y, including improve (T1: having any problem, T2: no problem), no change (T1 and T2 same), and worsen (T1: no problem, T2: having any problem), Supplementary Table S3 presents changes in each comorbidity status
ρ (Rho): Spearman’s correlation coefficient, positive correlation coefficient indicates agreement between measures; negative correlation coefficient indicates disagreement between measures
VAS Visual Analogue Scale, LSS Level Sum Score, A higher LSS indicated a worse health state
