Figure 4:

Plots show segmental ventilation defect percentage (VDP) in plugged versus nonplugged segments in each of the eight individual participants (participants A–H) with identified mucus plugs. Horizontal lines represent the median, 25th percentile, and 75th percentile values. Each dot represents one individual bronchopulmonary segment. The number of plugs identified in each participant ranged from 1 to 11, as indicated in each subplot title, with a median value of 5.5 plugged segments. Median segmental VDP in plugged segments was higher than that in the unplugged segments in all but one participant (participant H, with only one mucus plug identified). In specific participants, there is considerable overlap in values for plugged versus unplugged segments, as in participant B, for whom nearly all segments have substantial segmental VDP, and in participant C, for whom all segments have relatively low segmental VDP.
