Table 2 Relative accuracy of estimated glomerular filtration rate (eGFR)

From: Change of renal function after short-term use of cardioprotective agents in patients with type 2 diabetes is not accurately assessed by the change of estimated glomerular filtration rate: an observational study

Relative accuracy n (%) For a given mGFR of 111 ml/min/1.73m2, the range of mGFR (ml/min/1.73m2) equals
P10** 80 (42%) 100 to 122
P15** 121 (64%) 94 to 128
P20** 145 (76%) 89 to 133
P25** 161 (85%) 83 to 139
P30* 171 (90%) 78 to 144
  1. *P30 is described as the percentage of estimated glomerular filtration rates (eGFR) that lie within ± 30% of the measured glomerular filtration rate (mGFR)
  2. **P10, P15, P20 and P25 corresponds to a limit of error of ± 10%, ± 15%, ± 20% and ± 25%
