Innate IL-10 responses in relation to increasing age in infancy.

Presented are the geometric means and 95% confidence intervals (pg/mL) for background-adjusted IL-10 responses. Mann-Whitney U tests for significant differences in log-transformed IL-10 levels compared to the “1–3 months” age group; and Spearman rho tests for significant correlations between log-transformed IL-10 levels and ordered age groups were conducted. Significance level is indicated where p<0.05 only (* p = 0.046; ‡ p = 0.022). ♦denotes LPS co-stimulation used.
