Fig 2. Receiver operating characteristic curves and the C-statistic (area under the curve) for the models predicting the risk of a ≥50% eGFR or ESRD using the Oxford (MEST-C) score with or without a maximal glomerular diameter (Max GD) ≥ 242.3 μm.

Adding a Max GD ≥ 242.3 μm to the MEST-C score significantly improved discrimination regarding the renal outcome, as measured by the change in the C-statistic from 0.657 to 0.772. eGFR: estimated glomerular filtration rate; ESRD: end-stage renal disease; Max GD: maximal glomerular diameter.
