Consistency of Mycobacterium tuberculosis-Specific Interferon-Gamma Responses in HIV-1-Infected Women during Pregnancy and Postpartum

Table 2

(a) Odds of consistently positive interferon-γ release assays in women associated with baseline magnitude of interferon-γ response >8 compared to ≤8 SFCs/well. (b) Odds of >50% postpartum visits with positive interferon-γ release assays in women with baseline magnitude of interferon-γ response >8 compared to ≤8 SFCs/well.

(a)

	Postpartum consistency of IGRAs
Interferon-γ response* (SFCs/well) during pregnancy	Yes	No	Odds ratio (95% confidence interval); 𝑃 value
>8	8	4	10.0 (0.85–117.0); 0.07
≤8	1	5

(b)

	Greater than 50% postpartum visits with positive IGRAs
Interferon-γ response* (SFCs/well) during pregnancy	Yes	No	Odds ratio (95% confidence interval); 𝑃 value
>8	10	2	5.0 (0.55–45.39); 0.15
≤8	3	3

Note: IGRA interferon-gamma release assay.
*Maximum of ESAT-6/CPF-10 minus negative control.
