Baseline and 2-wk endocannabinoid (EC) and EC-related compound concentrations in aspartame (Asp)- or high-fructose corn syrup (HFCS)-sweetened beverage groups. Between-group comparisons were conducted by repeated-measures analysis, and within-group differences from baseline were conducted by Studentʼs t-test. *P < 0.05, **P < 0.01. P values in parentheses reflect significance after removal of two outliers in Asp group.
