^{a}In CKD stage 1, equations 3 through 6 showed lower percentages of misclassification than equations 1 and 2 (*P*< 0.05 for equations 3 and 4; NS for equations 5 and 6). In CKD stage 2, equations 3 through 6 achieved lower percentages of misclassification than equations 1 and 2 (*P*< 0.05 for all).
