Table 6 Percentage of discordant patients according to the two equations considered

From: Creatinine-or cystatin C-based equations to estimate glomerular filtration in the general population: impact on the epidemiology of chronic kidney disease

  MDRD CKD-EPI CKD-EPI Cys CKD-EPI mix
MDRD XXXXXXXXX    
CKD-EPI 3.3% (99.98%) XXXXXXXXX   
CKD-EPI Cys 11.2% (87.1%) 8.29% (81.5%) XXXXXXXXX  
CKD-EPI mix 8.63% (96.7%) 5.58% (92.8%) 2.71% (44.7%) XXXXXXXXX
  1. In the brackets is the percentage of patients, among these discordant patients, yielding a positive result (eGFR below 60 mL/min/1.73 m2) when the equation in the column is considered (although the equation in the same line gives an eGFR greater than 60 mL/min/1.73 m2).
