CD8A and Esophageal atresia: The results of these correlations are illustrated in Fig. 5B. A positive correlation was found between the total HIV-1 DNA copies found in PBMCs of EA patients and the frequencies of CD8+ EM (P = 0.03) and total CD8+ HLA-DR+ T cells (P = 0.05), whereas an indirect correlation was detected with CD8+ TEMRA T cells (P = 0.03).
