Youth whose families participated in SAAF had less inflammation than did controls. The endpoint is a composite indicator of inflammation, formed by summing each subject’s z-scored values for interleukins-1β, 6, 8, and 10, plus tumor necrosis factor-α and IFN-γ. Dots represent individual data points. Within each group, the wide horizontal bar is the mean composite score, and the error bars reflect 95% confidence intervals.
