CD4 and bacterial pneumonia: The death cases were characterized by older age (P < 0.001), a lower CD4+ T cell count (P < 0.001), a lower rate of cART administration (P = 0.029), being more prone to diagnosis delay (P < 0.001), complication with bacterial pneumonia (P < 0.001) and clinical manifestations of dyspnea (P = 0.033), a reduced presence of high fever (P = 0.044), more extensive lesions (P = 0.006) and pulmonary atelectasis (P = 0.039) shown on chest CT (Table 1).
