Characteristics of MDR spinal TB
| Patients (272) | Patients (3137) | ||
|---|---|---|---|
| N | % | % | |
| MDR-STB | 272 | 100 | 8.67 |
| First-line drugs | |||
| Isoniazid | 187 | 68.75 | 5.96 |
| Rifampicin | 156 | 57.35 | 4.97 |
| Streptomycin | 114 | 41.91 | 3.63 |
| Second-line drug | |||
| Levofloxacin | 79 | 29.04 | 2.52 |
| Rifapentine | 62 | 22.79 | 1.98 |

MDR: multi-drug resistant; TB: tuberculosis.
The first column represents the patients with MDR spinal TB (272); the second column represents all patients with spinal TB (3137). The data is the ratio of the number of patients with each drug resistance to the total number of patients. For example: 272/3137 = 8.67%; 187/272 = 68.75%; 187/3137 = 5.96%. Because each patient is resistant to two or more drugs, the sum of the number of patients who were resistant to each drug exceeds the total number (272).
