answers 402

Mehran 2004 contrast-induced nephropathy risk score after PCI (eGFR model B). Points from hypotension, IABP, CHF, age >75, anemia, diabetes, contrast volume (1 per 100 mL), and caller eGFR. Returns integer score (max 41), risk group (low ≤5 through very_high ≥16), and development-set CIN percent. Not a CKD diagnosis; magent does not measure contrast or compute eGFR.
