Incidence of fibrotic ILD (F-ILD), idiopathic pulmonary fibrosis (IPF), and death according to the age and the counts of lymphocytes and neutrophils in the BAL of patients. (A) Incidence of F-ILD, IPF, and death (estimated as the percentage of the sum of deaths divided by the sum of follow-up times of patients) according to the age of ILD patients; (B) incidence of F-ILD and IPF in patients according to the counts of lymphocytes (<7%, 7–20%, or >20%) and neutrophils (<5%, 5–15%, or >15%) in the BAL at diagnosis. p < 0.001 in the Chi-square test; and (C) Kaplan–Meier and Log-Rank tests for overall survival (OS) of the general population, ILD patients without fibrosis, and F-ILD and IPF patients. Pulmonary fibrosis was computed with the presence of reticular changes, traction bronchiectasis, and honeycombing in the radiological study. The 75th percentile OS (Q3–OS) is shown for each case.
