2.8. Power Calculation
T2DM
The power calculation was performed for our primary endpoint, which was a 240 min incremental area under the curve (iAUC) for glucose during an OGTT. In a previous study investigating the effect of stevioside in T2DM, we identified a minimally relevant difference for a 240 min iAUC for a test meal of 18% (iAUC 638 ± 55 versus 522 ± 64 mmol/L × 240 min (control versus stevioside);
