Fig. 5. Plasma levels of soluble L-selectin from African-American subjects reading magazines (o) or undergoing a speech task (). Data are presented as mean (ng/ml) ± SE. Blood was drawn at BL, immediately after the speech/reading task (0), and 20 minutes after the task (20). The two groups showed a differential change across the session with a significant group x time interaction (F(2,54) = 3.1, p = .05).
