Definition of abbreviations: FEV1 = forced expiratory volume in 1 second; FVC = forced vital capacity; LAS = lung allocation score; SD = standard deviation.
*
Positive values indicate greater values with a race-neutral approach.
†
P values are based on Student’s t tests.
‡
Positive values indicate greater values among White patients.
