^aFor chest x ray, laterality was not reported in 34 patients. Chest x ray was not done in 5 patients.

^bUnilateral was the presence of abnormalities in one lung;

^cbilateral was presence of abnormalities in both lungs;

^dmultifocal was abnormalities in multiple foci in same or both lungs. They are mutually exclusive.

^eDescriptive variables, mutually exclusive

^fCT scan was only done in 70 patients and laterality with or without multifocality was reported in all of them.
