Box plots (median, 1st and 3rd quartiles, minimum and maximum) of the residual volume/total lung capacity (RV/TLC) ratio according to the phase III slope of the nitrogen single-breath washout (phase III slope). A significant difference was found between patients with phase III slope < 120% and patients with phase III slope > 120% (P = 0.024)
