Linear mixed effects models for change in FVC% over time in non-IPF f-ILD patients, showing slower FVC decline in treated vs. non-treated group: (a) across the whole cohort, with FVC% slope in the treated group being less negative ( P < 0.001); (b) among the patients with initially high inflammatory marker status, where FVC% slope in the treated group turned positive (P = 0.004); and (c) among the patients with initially low-to-normal inflammatory marker status, where FVC% slope in the treated group was less negative (P = 0.001)
