Statistics are presented as mean ± standard deviation [range], median [interquartile range], and n (%). *, N=45. TB, tuberculosis; FVC, forced vital capacity; FEV1, forced expiratory volume in 1 second; PEF, peak expiratory flow; FEF 25–75, forced expiratory flow between 25% and 75% of vital capacity.
