Figure 1.

Differences in baseline fitness among the study groups using either body mass index or percent body fat to define obesity. The circled points and error bars represent adjusted means and 95% confidence intervals, respectively. The model (one-way analysis of covariance) was adjusted for age, sex, examination year, smoking, and alcohol consumption. Pairwise comparisons were adjusted for the Bonferroni correction. METs, metabolic equivalents, 1 MET = 3.5 mL of oxygen uptake/kg/min.
