Bolded items are statistically significant at the 0.05 level.
ELISPOT response reported as the median number of spot forming units per well, with interquartile ranges displayed in parentheses.
p-value from repeated measures linear regression models adjusting for gender.
ELISA responses reported as pg/ml, with interquartile ranges displayed in parentheses. Negative values indicate that unstimulated secretion values were higher than stimulated values. NT = not tested.
