* Pleural effusion or intrathoracic (mediastinal or hilar) nodes without opacity in the lung parenchyma were considered normal CXR. Abnormal CXR scoring were defined using the Timika scoring system (https://pubmed.ncbi.nlm.nih.gov/20861290/).
EPTB = extrapulmonary TB; CXR = chest radiograph; AFB = acid-fast bacilli; NAAT = nucleic acid amplification test.
