Figure 1. Daily mean glucose levels of type 1 and type 2 diabetic patients on the first (sample 1, S1) and last (sample 2, S2) days of hospitalization. There was a significant reduction in the daily mean blood glucose levels in both type 1 and 2 diabetic groups. The Student t-test was used. The horizontal lines indicate the mean for each group.
