However, for mean concentrations of IL-8, the analysis revealed a weak, but significant “Group” and “Status of BoDV-1 infection” interaction [F(1, 58) = 5.97, p < 0.05, η2p = 0.09], with higher IL-8 concentrations in BoDV-1 negative MDD patients compared to BoDV-1 positive MDD patients (|Mean|Diff = 3.34, p < 0.01) or BoDV-1 negative adults without MDD diagnosis (|Mean|Diff = 3.43, p < 0.01; see Table 1). Here, CXCL8 is linked to infection.
