Abbreviations: BCG, bacille Calmette-Guérin; BMI, body mass index; Epi, epidemiologic; NA, not applicable; OR, odds ratio; RSTR, resister phenotype; SD, standard deviation; TB, tuberculosis.
aRisk score was generated based on the age of the subject during the original study TB household contact study (phase 1); age determined the values of the variables of this score (eg, proximity to and characteristics of the index case). Analysis was stratified by age in phase 1, with children defined as <15 years old.
