Fig. 2From: Using the kidney failure risk equation to predict end-stage kidney disease in CKD patients of South Asian ethnicity: an external validation studyCalibration plots of predicted vs observed risk using pseudo-observations. Observations of risk that were very high were due to extreme ACR values, which skewed the pseudo-observations. A total of 96.9% of risks were < 15% in the white cohort, and 93.0% were < 15% in the South Asian cohort, so inspecting calibration at the higher risks is unreliable in this datasetBack to article page
