Table 8.
Incidence of complications: Pooled estimates of incidence of lung cancer after successful TB treatment in studies also reporting incidence in non-TB controls.
| Population | Number of study populations | Proportion of participants with lung cancer (n/N) | Lung cancer per 1000 PY (95% CI) | Incidence rate ratio (95% CI) | Incidence Rate Difference per 1000 PY (95% CI) |
|---|---|---|---|---|---|
| TB | 4 | 290/89,429 | 3.9 (2.5–6)a | 4 (2.1–7.6) | 2.7 (1.2–4.2) |
| Controls | 4 | 3197/7,288,122 | 1 (0.4–2.4)b | NA | NA |
Pooled estimates included all persons at risk for complications (I.e., the denominator in these estimates was all persons post-TB in the studies reporting on post-TB complications).
TB, tuberculosis; PY, person-years; CI, confidence interval; NA, not applicable.
a
Prediction interval: 0.49 to 30.64, I2 = 92.3%.
b
Prediction interval: 0 to 7.4, I2 = 99.9%.
