A vectorised function to calculate raw EPTS scores for norm-related prediction of patient survival after adult renal transplants. This function generates the raw EPTS scores which can be converted to percentiles using the lookup table on the OPTN website at https://optn.transplant.hrsa.gov/media/2973/epts_mapping_table_2018.pdf
raw_epts(age, dm, prev_tx, dx)
| age | numeric vector of patient age in years (with decimals) |
|---|---|
| dm | numeric vector of whether patient diabetic (1 = yes, 0 = no) |
| prev_tx | numeric vector of whether patient has a previous solid organ transplant |
| dx | numeric vector of duration of dialysis in years (with decimals) |
numeric vector of raw EPTS scores
