(a) Forest plots of the effect of cell type on FVC change and (b) Effect of cell type on DLCO change. Linear mixed-effects model was used to assess the association between iBAL cell type and changes in lung function over time. Both models were corrected for the days from the first and last lung function tests. Data are presented on the Y-axis as all measured BAL differential cells and lymphocyte subsets. The X-axis represents the mean and 95% confidence interval. NK = natural killer
