CXR = chest radiograph; HbA1C = glycosylated hemoglobin; LAP = lymphadenopathy; TB = tuberculosis.
a Minimal lesions = an area less than that above a horizontal line across the 2nd chondrosternal conjunction of one lung; Moderately-advanced lesions = an area more than minimal lesions but less than one entire lung; Far advanced lesions = an area equivalent to or greater than one lung.
