Characteristics of the French and the Swedish cohort of children and adolescents.

<p>BSA =  body surface area, BMI = body mass index, IQR = interquartile range, mGFR = glomerular filtration rate measured by inulin clearance.</p

Agreement between formulas and inulin clearance according to age subgroup in the French and the Swedish cohorts.

<p>CCC = concordance correlation coefficient (CCC = ρ×Cb), ρ = Pearson coefficient, CI = Confidence Interval, Cb = factor for Pearson coefficient correction in CCC - *p<0.05 between formulas.</p

Agreement between formulas and inulin clearance according to the GFR group in the French cohort and estimation of the diagnostic ability of the two formulas according to the CKD stage.

*<p>p<0.05 between Schwartz-Lyon formula and 2009-Schwartz - Mean ratio = mean ratio (eGFR/mGFR) value, AUC = area under ROC curves, 95% CI = 95% Confidence Interval.</p

Bland and Altman plots showing the ratio estimated GFR/measured GFR versus the measured GFR as gold standard in the Sweden cohort.

<p>Panel A: 2009-Schwartz in children. Panel B: Schwartz-Lyon in children. Panel C: 2009-Schwartz in adolescents. Panel D: Schwartz-Lyon in adolescents.</p

Formulas used for estimating the glomerular filtration rates.

<p>Height is expressed in cm. PCr = Plasma creatinine, expressed in µmol/L.</p
