FIGURE 3.

“Heatmaps” depicting correlations between a) lung function variables measured at home and in clinic at different time-points (r≥0.5 for all correlations), b) changes from baseline in lung function variables measured at home and in clinic at different time-points, and c) rates of decline in lung function variables measured at home and in clinic at different time-points. FVC: forced vital capacity; FEV₁: forced expiratory volume in 1 s; FEV₆: forced expiratory volume in 6 s. Darker shades of red or blue indicate stronger positive or negative associations, respectively.
