CD4 and tuberculosis: In our multivariable competing risk regression model, factors significantly associated with TB incidence were BMI < 18 kg/m2 (Underweight) (aSHR = 8.21, 95% CI 2.43–27.73, p = 0.001) compared to BMI 18–23 kg/m2 (Normal weight), history of substance use (aSHR = 6.03, 95% CI 1.16–31.21, p = 0.032), and time updated CD4 count < 50 cells/m3 (aSHR = 18.23, 95% CI 3.35–99.16, p = 0.001) or 50–200 cells/m3 (aSHR = 5.43, 95% CI 0.98–29.92, p = 0.05) compared to CD4 > 350 cells/m3 (Table 4).
