Effect of known TB contact and TBI prevalence of municipality on risk factors associated with children’s odds of TBI

Variable	Known TB contact OR (CI 95%)	No known TB contact OR (CI 95%)
Age 5 years or older. Referent group: younger than 5 years	n/a*	1.6 (1.1–2.3)**
Mother or primary caregiver with known TB. Referent group: no reported TB contact or the known TB contact is not a primary caregiver or mother	1.8 (1.2–2.7)**	n/a*
High-burden municipality. Referent group: low-burden municipality (TBI prevalence < 7%)	1.6 (1.1–2.4)**	2.8 (2.0–3.9)***

Variable	High–TBI-burden municipality (≥ 7%) OR (CI 95%)	Low–TBI-burden municipality (< 7%) OR (CI 95%)
Age 5 years or older. Referent group: younger than 5 years	1.4 (1.0–1.9)**	n/a*
Known contact with TB. Referent group: no reported TB contact	3.4 (2.4–4.8)***	6.1 (3.4–11.1)***
Displaced from home following earthquake. Referent group: no reported displacement	n/a*	0.5 (0.3–0.98)**
Mother or primary caregiver with known TB. Referent group: no known TB contact or known TB contact that was not either subject’s mother or other primary caregiver	1.8 (1.1–3.1)**

OR = odds ratio; TBI = tuberculosis infection.

^*n/a indicates P-value > 0.05.

^**P-value < 0.05.
