Ten-year cumulative risks of ESRD in patients with T1D were calculated by actuarial methods according to CKD stages determined jointly by eGFRcrea and eGFRcyst. The pattern of differences was similar in the Joslin and FinnDiane cohorts of T1D, so the cohorts were pooled as a single cohort. The percentages on the boxes are 10-year cumulative risks of ESRD. : Concordant CKDcyst and CKDcrea stages. : CKDcyst stage is higher (eGFR is lower) than the CKDcrea stage. : CKDcyst stage is lower (eGFR is higher) than the CKDcrea stage.
