^aConcentrations were transformed using the Boxcox transformation (Box and Cox) to normalize the distribution of concentrations but untransformed values are presented. Values were mutually corrected for sponge type, volume of cervical secretions, collection order of the sponge, and participant. P values of <0.05 were considered statistically significant.

^bP values were 0.1 for IgA, 0.5 for IgG, 0.9 for IL-10, and 0.9 for IL-12.

^cP values were <0.0001 for IgA and IgG and 0.02 for IL-10 and IL-12.

^dP values were 0.2 for IgA, IL-10, and IL-12, and 0.1 for IgG.
