On the other hand, neutrophils (10.6 × 105 ± 1.4 × 105 vs. 18.6 × 105 ± 3.7105; p = 0.04) and CD4+ T cells (4.4 × 104 ± 5.7 × 103 vs. 7.4 × 104 ± 1.4 × 104; p = 0.04) counts were significantly lower in the exercise group compared with control at day 2 after infection (Fig. S6D, http://links.lww.com/CCM/H474). The gene discussed is CD4; the disease is infection.
