Population | Adult patients with respiratory symptoms |
Index test | Trial-of-antibiotics (any course of broad-spectrum antimicrobial given with the goal of ruling out TB in a symptomatic adult) |
Reference test | Any mycobacteriology test (we expect smear microscopy, smear microscopy using a fluorescent microscope, Cepheid GeneXpert, and mycobacterial culture) |
Outcome | Proportion of mycobacteriology-positive or mycobacteriology-negative participants correctly identified by trial-of-antibiotics (sensitivity and specificity) |
Design | Cross-sectional, cohort, and randomised controlled studies |
