Abbreviations: HAZ, height-for-age z-score; IQR, interquartile range; WAZ, weight-for-age z-score; TB, tuberculosis; TST, tuberculin skin test.
TST could not be administered to all children because of a national tuberculin stock-out; denominator represents total number of children who had a TST placed within each subgrouping.
