  • Higher value, greater amount (or higher score) on a particular variable. KAS, Kidney Allocation System; SHR, subdistribution hazard ratio.

  • a Main event, received a transplant; competing event, died, censoring, still on waitlist or other removal.

  • b Sample size used for Models 1, 2, and 3: n=997 (i.e., those with complete data on all variables; 346 received a transplant, 385 died, 266 censored).

  • c Final status after KAS refers to whether the patient’s ultimate outcome (i.e., transplant, died, censored) occurred either before or after the KAS policy changes of 2014 to all of the tables that include this variable.

  • d The SHR for these variables are per one-point higher in each scale.
