Results are shown as mean (SEM).

Within differences for R_a palmitate (P < 0.01), epinephrine (P < 0.01), insulin (P > 0.3), and glucose (P < 0.01) for Caucasians and African-Americans.

African-American vs. Caucasian.

Overall interaction for time point by race for R_a palmitate (P = 0.4), epinephrine (P = 0.2), insulin (P = 0.2), and glucose (P = 0.3).
