Table V.
Plasma glucose and insulin responses to an OGTT conducted prior to the start of intervention (baseline) and after 8 weeks of intervention with the placebo (placebo group) or the AP supplement (AP group) as revealed by glucose AUC0→2h and insulin AUC0→2h.
| Variable | Intervention period | Measures of variance | Between-group difference in variance (P-value) | |
|---|---|---|---|---|

| Placebo group (n=17) | AP group (n=17) | |||
| Glucose AUC0→2h (mg/dl/h) | Baseline | 397.2±17.1 | 377.2±14.3 | |
| 8 weeks | 389.7±17.7 (0.622) | 347.1±14.2 (0.018) | ||
| Change from baseline | −7.4±14.8 | −30.1±11.4 | 0.234 | |
| Insulin AUC0→2h (μU/dl/h) | Baseline | 48.2±5.0 | 72.4±11.0 | |
| 8 weeks | 40.5±6.8 (0.159) | 50.0±8.5 (0.009) | ||
| Change from baseline | −7.6±5.2 | −22.3±7.6 | 0.119 | |
All values are expressed as the mean ± standard error of the mean (SEM). P-value of within-group differences in measurement from baseline was assessed by the Student’s paired t-test and shown in parentheses. Baseline values were determined prior to the start of intervention. OGTT, oral glucose tolerance test; AP, acacia polyphenol; AUC, area under the curve.
