“…PubMed research (last accessed July 2010) recovered only 12 studies with mGFRs Ͼ100 reporting this performance of the CG and MDRD formulas, and their results are presented in Table 2 (6,44,72,90,92,95,99,(103)(104)(105)(106)(107). Comparing CG versus MDRD formula in studies with data for both formulas (6431 subjects) showed similar overall proper classification of the subjects, 64% versus 63%, range 55% to 72% versus 53% to 71%, respectively (6,72,92,95,99,(103)(104)(105)(106)(107). The best performance of CG and MDRD equations was in mGFR group 30 to 59 ml/min per 1.73 m 2 , whereas the worst one was in mGFR groups Ͻ15 and Ͼ90 ml/min per 1.73 m 2 , respectively.…”
