CD4 and pulmonary tuberculosis: Although concomitant pulmonary TB was more common in HIV-infected patients (32.6% vs. 29.3%; p = 0.4), it was not associated with increased mortality nor with degree of immunosuppression, as measured by CD4 cell count, though it should be taken into consideration that the majority of patients in both the deceased and living groups had CD4 counts less than 200.
