Table 2. Characteristics of PTB and non-TB patients.
Patients with respiratory symptoms (n = 892) were screened for pulmonary tuberculosis (PTB) and classified as non-PTB or PTB according to culture positivity. Frequency data were compared using the Fisher’s exact test and continuous variables (age and BMI) were compared using the Mann-Whitney test. See Table 1 for abbreviations.
