Unpaired student’s t-tests were used for analysis. PROC GLM was used to build models to determine differences in macronutrient and body composition variables between TB subjects and household contacts. Model I adjusted for age and sex, while model II adjusted for age, sex, employment status and smoking. We also tested for interactions with sex.
