The following errors have recently been discovered. None of the errors substantially affects the results or conclusions of the study (1).
In Table 4, there is a typographical error in the number of patients with concordant estimated glomerular filtration rate (eGFR) of 30 to 59 mL/min per 1.73 m2 (using CKD-EPI [Chronic Kidney Disease Epidemiology Collaboration] and MDRD [Modification of Diet in Renal Disease] study equations) with measured GFR >90 mL/min per 1.73 m2. The number of patients should be 18 (0.5%) rather than 118 (3.0%).
In Appendix Table 4, 125 patients enrolled in the Nephrotest study were included twice, so the total number of patients study should be 313 rather than 438. Consequently, in Table 1, the number of patients included in the validation data set should be 3771 rather than 3896. This error does not affect the validation of the new equation.
