| Radiological findings | DS-TB (n=18) |
MDR-TB (n=16) |
p-value |
|---|---|---|---|
| Cavity prevalence [n(%)] | 6 (33.33%) | 13 (81.25%) | 0.007* a |
| Cavity number (n) | 0.50±0.79 | 2.44±2.25 | 0.001* b |
| Bilateral lung lesions [n(%)] | 2 (11.11%) | 5 (31.25%) | 0.214c |
| Maximum diameter of cavity (mm) | 8.33±13.39 | 22.19±18.79 | 0.012* b |
| Sum of cavity diameters (mm) | 10.56±16.97 | 34.38±29.26 | 0.006* b |
Notes: *Represents p-value less than 0.05. aFisher exact test was used for categorical data. Comparison of proportions of patients with lung cavities between the DS-TB group and MDR-TB group.bMann-Whitney test was used for nonparametric unpaired groups. cFisher exact test was used for categorical data. Comparison of proportions of patients with bilateral lung lesions between the DS-TB group and MDR-TB group. Data are shown as mean ± SD or percentages.
Abbreviations: DS-TB, drug-sensitive tuberculosis; MDR-TB, multidrug-resistant tuberculosis.
