Among HIV-infected participants, over 98% were on ART, 86% were virologically suppressed with a median viral load of <20 copies/mL and a median nadir CD4+ T cell count of 330 cells/mm3 (interquartile range [IQR], 167 to 544 cells/mm3) and 383 cells/mm3 (IQR, 222 to 520 cells/mm3) among COPD-positive and -negative individuals, respectively. Here, CD4 is linked to chronic obstructive pulmonary disease.
