Kaplan-Meier survival curve. Patients with and without any complication are represented by the red and blue curves, respectively. Patients with a complication on any CXR or CT during admission had no difference in overall survival (A) (log-rank p = 0.94). Patients with a complication on initial CXR had worse survival (B) (log-rank = 0.01), but there was not survival difference after adjusting for age, sex, respiratory rate, body mass index, diastolic blood pressure, and history of smoking, hypertension, coronary artery disease, or heart failure (adjusted HR 1.11 [0.62–1.97], p = 0.74).
