% Other: The number of patients who neither died nor were transplanted in a particular status level, divided by the number of patients ever in that status level, multiplied by 100.

% Died Post-TX: The number of patients who died following transplantation, divided by the number of patients ever transplanted in that status level, multiplied by 100 for a particular status level at the time of transplantation.

% Male: The percentage of male patients in a particular status level.

% B or AB: The percentage of patients with blood type B or AB out of all patients ever in that status level.

% Black: The percentage of African American patients ever in that status level.

Age: The average for patients in that status level.

MMLE: Maximum marginal likelihood estimate—an estimate of an unknown parameter in a statistical model that produces the greatest probability of the model given the date.

SE: Standard error—a measure of uncertainty in an estimated parameter of a statistical model.

P: The probability associated with a test of the null hypothesis that the true parameter value is zero.

N: The number of patients ever listed in that status category during the period analyzed.

OPO: Organ procurement organization. The numbers in this column are coded. To conduct the analysis, the identities of 52 OPOs were encrypted (10 OPOs do not perform liver transplants). Therefore, the number assigned to each OPO does not match the number assigned to OPOs on the UNOS regional map found in Chapter 1 (Figure 1-1).

Total No. of TX: The total number of transplants performed in an OPO regardless of status level.

Total No. of Listings: The total number of patient listings in an OPO regardless of status.

Overall Percentage: The total number of transplants divided by the total number of patient listings for a particular OPO regardless of listing or transplant status.
