Cockcroft Gault ABW | Men: ((140—age) x ABW) / (Scr x 72); women: ((140—age) x ABW) / (Scr x 72) x 0.85 |
Cockcroft Gault IBW | Men: ((140—age) x IBW) / (Scr x 72); women: ((140—age) x IBW) / (Scr x 72) x 0.85; with IBW = 50 kg + (0.906 x (height-152.4)) in men and 45.5 kg + (0.906 x (height-152.4)) in women |
Cockcroft Gault LBW | Men: ((140—age) x LBW) / (Scr x 72); women: ((140—age) x LBW) / (Scr x 72) x 0.85; with LBW = (9270 x ABW) / (6680 + (216 x BMI)) in men and (9270 x ABW) / (8780 + (244 x BMI)) in women |

Salazar-Corcoran | Men: ((137—age x ((0.285 x weight) + (12.1 x height2))) / (51 x Scr); women: ((146—age x ((0.287 x weight) + (9.74 x height2))) / (60 x Scr) |
MDRD | Men: 186 x Scr−1.154 x age−0.203; women: 186 x Scr−1.154 x age−0.203 0.742 |
CKD-EPI | Women when Scr ≤0.7: 144 x (Scr / 0.7)−0.329 x 0.993age and when Scr >0.7: 144 x (Scr / 0.7)−1.209 x 0.993age; men when Scr ≤0.9: 141 x (Scr 0.9) −0.411 x 0.993age and when Scr >0.9: 141 x (Scr / 0.9)−1.209 x 0.993age |
Ideal body weight was calculated using the formula by Devine (34) with height measured in centimeters. In the Salazar-Corcoran equation, weight is expressed in kilogram and height in meter.
Scr = serum creatinine, AWB = actual body weight, IBW = ideal body weight, LBW = lean body Weight, ADBW = adjusted body weight, NBW = no body weight, MDRD = Modification of Diet in Renal Disease, CKD-EPI = Chronic Kidney Disease Epidemiology Collaboration.
