An adult with type 2 diabetes takes the same medication during two periods. The table shows mean results recorded over each period.
| Period | Carbohydrate eaten at breakfast in g | Physical activity during the next two hours in min | Blood glucose before breakfast in mmol dm−3\mathrm{mmol\,dm^{-3}}mmoldm−3 | Blood glucose two hours after breakfast in mmol dm−3\mathrm{mmol\,dm^{-3}}mmoldm−3 |
|---|---|---|---|---|
| 1 | 82 | 5 | 6.7 | 10.1 |
| 2 | 48 | 30 | 6.8 | 7.9 |
