WebSubjects with SSc-ILD and forced vital capacity (FVC) between 50 and 80% of the predicted (%pred) value were randomised in 1:1 ratio to receive either pirfenidone (2400 mg/day) or placebo for 6 months. Primary outcome was the proportion of subjects with either stabilisation or improvement in FVC at 6 months. WebThe two stepwise analyses converged to the same model. Seventeen variables were used as covariates including lung function variables as continuous variables (FEV 1 % pred, FVC % pred, RV/TLC), comorbidities as individual variables and BMI as a categorical variable (low <18.5 kg/m 2; obesity >30 kg/m 2). The mMRC dyspnea scale was also used.
