CD4 and tuberculosis: Females (unadjusted IRR, 95% CI = 0.53, 0.38 to 0.73) and participants with higher CD4 (unadjusted IRR, 95% CI = 0.56, 0.50 to 0.64) were less likely to develop incident TB, while those with a BMI < 18.5 kg/m2 were more likely to develop TB (unadjusted IRR, 95% CI = 2.02, 1.33 to 3.08).
