Figure 1 MBF and MVO₂ in obese and nonobese men and women

Panel A shows MBF, which we quantified using positron emission tomography, in the 4 subject groups. The p values for the pairwise comparisons are shown. The obese women had the greatest MBF, which was significantly greater than in the nonobese women or the obese men. The nonobese women also had greater resting MBF than the nonobese men. Panel B shows MVO₂ levels in the groups, as determined with the utilization of positron emission tomography. Obese women had the greatest MVO₂, which was significantly greater than the nonobese women and the obese men. Nonobese women also had greater MVO₂ than the nonobese men. MBF = myocardial blood flow; MVO₂ = oxygen consumption.
