Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| postprandial glycemic response | 14 days | postprandial glycemic response (PPGR) : PPGR refers to the dynamic changes in blood sugar levels after eating, reflecting the extent to which food affects blood sugar. PPGR is mainly determined by calculating the area under the Incremental curve (Incremental AUC, iAUC) of blood glucose. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| postprandial blood glucose peak | 14 days | The maximum postprandial blood glucose measured by CGM |
