Data are from an intent-to-treat analysis. Proportions of identified child contacts who initiated TPT or TB treatment are presented for each cluster (clinic). The unweighted mean of the clinic-level proportions is displayed by arm. An unpaired t test was used to assess the significance of the difference of the mean proportions between arms.
Abbreviations: CI, confidence interval; TB, tuberculosis; TPT, tuberculosis preventive therapy; TST, tuberculin skin test.
