Analyses
REGRESSION
Analyses were based on data from patients who received ≥1 dose of trial drug. The rate of decline in FVC (mL/year) over 52 weeks was analysed in patients with RA-ILD using a random coefficient regression model (with random slopes and intercepts) including baseline FVC (mL), HRCT pattern (UIP-like fibrotic pattern or other fibrotic patterns) and treatment, and treatment-by-time and baseline-by-time interactions. Subgroup analyses used the same model but with interaction terms for baseline-by-time, treatment-by-subgroup, and treatment-by-subgroup-by-time interaction. In subgroups by CRP at baseline, the interaction
