Association between diabetic disease and type of tuberculosis
| Pulmonary TB, smear positive n (%) | Pulmonary TB, smear negative n (%) | Pulmonary TB, Only 1 smear n (%) | Pulmonary TB, smear not performed n (%) | Extra-Pulmonary TB n (%) | Relative risk (95% confidence interval)* n (%) | |
|---|---|---|---|---|---|---|
| Patients with diabetes | 60 (59) | 9 (9) | 7 (7) | 5 (5) | 20 (20) | 1.21 (1.04–1.40) |
| Patients without diabetes | 80 (46) | 31 (18) | 14 (8) | 12 (7) | 37 (21) | Ref |
Relative risk for patients with diabetes presenting as smear positive restricted to those who were either smear positive or smear negative 60/69 (87%), as compared to patients with non-diabetes 80/111 (72%).
