IHC findings in control and case groups. The number of cells represents the number of cells (whether stained or not) in each square, as described in the methods. Each square in all slides was approximately equal to 0.7980 mm². The number of bronchioles is represented in a slide observed in a low-power field view. ^∗𝑃<0.05 compared to the relevant control group.
