Baseline characteristics of donors and recipients of lungs with and without incidentally discovered pulmonary embolism (PE). Values are presented as n (%) or mean ± standard error of the mean. PE+, lungs with incidentally discovered donor PE. PE−, lungs without incidentally discovered donor PE.
*
Denotes donors with a smoking history ≥ 20 pack years (missing data in 2 donors). The denominator for the percentages is the sum of patients across all categories in the PE+ or PE− group, respectively, excluding missing values. PE, pulmonary embolism; ECMO, Extracorporeal Membrane Oxygenation; CMV, cytomegalovirus; mPA, mean pulmonary artery.
