A wrapper for the vectorised function meld() to calculate the MELD score, but using mg/dl for bilirubin and creatinine. If the patient is on CVVH or has been dialysed at least twice in the same week, the dialysis argument should be set to 1, which changes the creatinine level used in the formula to 4mg/dl. Following UNOS guidelines, the values for INR as well bilirubin and creatinine are set to a minimum value of 1 if less than 1.0
meld_US(INR, bili, creat, dialysis)
numeric vector ofINR
numeric vector of bilirubin in mg/dl
numeric vector of creatinine in mg/dl
numeric vector of whether on dialysis/CVVH (1 = yes, 0 = no)
