Figure 8.
Shown are the levels for fractional myocardial glucose uptake and glucose utilization/plasma insulin, respectively, for the 4 groups. Obesity's and gender's significant interaction in the prediction of glucose uptake (P < .05) is shown graphically because both the magnitude and direction of the effect of obesity on myocardial glucose uptake differ in men and women. Obese men have lower uptake than nonobese men; obese women, however, have greater uptake than nonobese women. Obesity and gender also interacted in determining glucose utilization/plasma insulin (P < .01), as shown by the magnitude of the difference between the obese and nonobese men and that between the obese and nonobese women.
