Quantitative TB antigen responses in QGIT converters from negative at entry to positive at delivery. Data were derived from 19 participants, including 11 in the immediate and 8 in the deferred IPT arms. Each point indicates TB-nil responses at the time point designated on the abscissa. The lines connect data from individual participants. The ordinate was organized in segments separating QGIT-negative results <0.35 IFNγ U/mL from positive results. Three participants in each arm maintained QGIT positivity postpartum; 6 participants in the immediate arm, and 5 in the deferred arm reverted to QGIT-negative postpartum; and 2 participants in the immediate arm lacked postpartum data.
