CD40LG and infection: A household with reported member(s) seeking clinical care for an infection origin in the past year had 2.17 times the adjusted odds (p-value = 0.0094; 95% CI: 1.21 to 3.91) of antibody-positive status for either ELISA, and the same pattern was seen for the odds of IgM antibody positive participants only (p-value = 0.0516; OR: 1.90, 95% CI: 0.99 to 3.62)—although this was only slightly higher than a 0.05 significance level.
