aBCG Bacille Calmette-Guérin, b PTB Pulmonary tuberculosis, c AFB Acid-fast bacillus; d CT Computed tomography. Risk factors for relapse: i) the presence of a cavity lesion on chest X-ray or chest CT, and ii) the result of a positive sputum culture after 2 months of anti-TB treatment. The high-risk group was defined when patients had both risk factors i) and ii). The moderate-risk group was defined when patients had either risk factor i) or ii), and the low-risk group had neither risk factor
