| The data are expressed as median (interquartile range) or numbers (percentage). Differences between the 2 groups were tested by corresponding statistical tests. The details are as follow: a the data were analyzed by Mann-Whitney U test for non-normally distributed continuous variables; b the data were analyzed by the χ test (minimum expected values ≥5); c the data were analyzed by Fisher’s exact test (minimum expected values BM – bronchomalacia; PTB – pulmonary tuberculosis; TBTB – tracheobronchial tuberculosis; NA – not available. | ||||
