Group distribution depending on the ‘ascending and descending’ periods of blood glucose levels before/during the surgery and blood glucose dynamics from T1 to T4.

U-group (blood glucose levels-ascending group, Up, n = 7) has the calculated value (the average value at the time of T1 and T2 subtracted by the average value at the time of T3 and T4) is above 0 and D-group (blood glucose levels-descending group, Down, n = 12 from 13; 1 sample, which showed a reduction of the glucose levels to 54 mg/dL at the time of T3, was excluded for next experiments because of its measurement error) has the calculated value is below 0.
