* Coefficients for these cohorts are shown to compare stability of the models across time. These coefficients differ from those actually used in previous CSRs because the data and models may have changed since the release of those CSRs.
** Reference for diagnosis group is glomerular diseases.
*** Ischemia time is centered on 13.53 hours.
