Renal dysfunction in patients with cirrhosis: Where do we stand?

Table 3 Formulas for estimating the glomerular filtration rate: modified diet in renal disease-4, modified diet in renal disease-6, chronic kidney disease epidemiology collaboration (mL/min per 1.73 m²)[118-120]

MDRD-4 formula (1)	186 × [creatinine (mg/dL)] -1.154 × [age (yr)] 0.203 × (0.742 if patient is female) × (1.21 if patient is black)
MDRD-6 formula (2)	170 × sCr (mg/dL)-0.999 × age-0.176 × 1.180 (if black) × 0.762 (if female) × serum urea nitrogen-0.170 × albumin 0.138
CKD-EPI equation (3)	141 × min (sCr/κ, 1)α× max (sCr/κ, 1)-1.209 × 0.993 Age × 1.018 (if female) × 1.159 (if black)

MDRD: Modified diet in renal disease; CKD-EPI: Chronic kidney disease epidemiology collaboration.
