Summary of concentrations of immune mediators and comparison of changes between the Acidform and HEC placebo groups.

Abbreviations: LLOD, lower limit of detection; Q3, 3rd quartile; n/a, not applicable.
aAs there was no significant interaction between treatment group and time, p-values <0.05 indicate that immune mediators changed over time, independent of whether participants applied Acidform or HEC placebo gel.
bTwo values were assigned the highest standard multiplied by the dilution.
cThree values were assigned the highest standard multiplied by the dilution.
dOne value was assigned the highest standard multiplied by the dilution.
