Usage

et_dri(age, cod, dcd, split, share, cit, ggt, rescue)

Arguments

age	numeric vector of patient ages in years
cod	character string vector of donor causes of death, one of "trauma", "anoxia", "cva" or "other"
dcd	numeric vector of whether DCD (1 = yes, 0 = no)
split	numeric vector of whether liver split (1 = yes, 0 = no)
share	character string vector of type of sharing, one of "local", regional" or "national"
cit	numeric vector of cold ischaemic times in hours
ggt	numeric vector of last pre-transplant serum gamma-GT level in IU/l
rescue	numeric vector of whether rescue transplant (1 = yes, 0 = no)

Value

numeric vector of ET-DRI scores

Examples

et_dri(age = 39, cod = "trauma", dcd = 0, split = 0, share = "local",
    cit = 8, ggt = 50, rescue = 0) # 1.00

et_dri(age = 25, cod = "cva", dcd = 0, split = 0, share = "local",
    cit = 8, ggt = 50, rescue = 0) # 1.15
