Table 3.

Frequency of each radiological findings in both lungs

	Right lung	Left lung	Expected number	p value	Correlation with tumor location
Air trapping	147	118	132.5	0.07	0.252
Lung fibrosis	124	83	103.5	0.004	0.004
Bronchiectasis	91	60	75.5	0.01	0.000
Tumor	28	14	21	0.03	–

These tables show that lung fibrosis, bronchiectasis, and tumor tend to develop more in the right lung. Moreover, cancer significantly develops in the lungs with radiological findings suggestive of lung fibrosis or bronchiectasis
