The average O2 supply rate was calculated for the arteriolar and venular end of the capillary bed as the product of RBC supply rate × O2 saturation for both control and prediabetes group. The O2 extraction ratio was calculated for the control and prediabetes group from the O2 saturation gradient from arteriolar (Sart) to venular (Sven) end divided by the arteriolar end O2 saturation, i.e., (Sart − Sven)/Sart. Box and whisker plots show median, upper and lower quartiles, and maximum and minimum values. So2, oxyhemoglobin saturation. *P < 0.05, different from control.
