The Effect of Candidate Sex on Liver Transplant Waiting List Events in the MELD Era. Several events may occur after registration on a liver transplant waiting list, including receipt of a liver transplant, death while waiting on the list, being removed from the list due to an illness precluding transplantation, or temporary inactivation for a period of time. We have modeled the effect of sex on each of these transitions, which is captured by the hazard ratios above each arrow. As in Figure 1, males have significantly higher transplant rates than females, and also have a significantly higher relative rate of removal from the waiting list. There are no statistically significant sex-based differences in waiting list mortality or inactivation, after adjusting for MELD score and geography.
