Step 1
Compare the glucose levels of person 1 with the glucose levels of person 2 after fasting for 12 hours.
Answer
After fasting for 12 hours, person 1 has a blood glucose level of 5.4 mmols/l, while person 2 has a level of 5.6 mmols/l. This shows that person 2 has a slightly higher blood glucose level than person 1.
Step 2
Compare the glucose levels of person 3 with the glucose levels of person 1, two hours after drinking 75g glucose.
Answer
Two hours after drinking 75g of glucose, person 1's blood glucose level is 6.4 mmols/l, whereas person 3's level is significantly higher at 12.1 mmols/l. This indicates that person 3 has a much higher glucose level compared to person 1 at this time point.
