Figure 2: Histogram comparison of the oxidation times of the hemoglobin of diabetics and nondiabetics blood by amyl nitrite*. *The mean diabetics oxidation time was 1.5 ± 0.2 min and the mean nondiabetics oxidation time was 3.1 ± 0.5 min. Based on Student’s t-test, a T value of 23.3 with 38 degrees of freedom was obtained with a difference between the two means that is statistically significant (p<0.05).
