n = number of lesions biopsied (except Chaddha [25] and Bajwa [29], where n = number of cases); NS = not specified; peripheral distribution = lesion in outer 1/3 of lung, or inaccessible using white-light and convex probe EBUS bronchoscope (Chen [23]). * Study did not report diagnostic sensitivity, but 14/15 lesions had diagnostic sampling. # Assuming the biopsy-proven inflammation (n = 13) was nondiagnostic vs. diagnostic. ¥ This is an ATS abstract.
