All patients who developed neutropenia at any time point after lung transplant were evaluated. Model was adjusted for age, gender, CMV infection, CLAD diagnosis, and gram-negative bacterial infection. Severe neutropenia was associated with poorer survival than no, mild or moderate neutropenia. Severe vs. no neutropenia: aHR=2.97 (1.05–8.41), p=0.04; Severe vs. Mild Neutropenia: aHR=14.51 (1.58–33.41), p=0.018; Severe vs. Moderate: aHR=3.27 (0.89–12.01), p=0.07.
