FIG. 2.

Odds ratio of metabolic syndrome based on 5% decrease in oxyhemoglobin saturation. We plotted the odds ratios and 95% confidence intervals for every 5% increase in oxyhemoglobin saturation. Relationship between oxyhemoglobin saturation and age and BMI in men and women. We plotted the mean oxyhemoglobin saturation for each 1 year or 1 kg/m² increased in age and BMI, respectively. This was done for men and woman independently. The graphs show a dose–response with increased age and BMI corresponding to incremental decreased oxyhemoglobin saturation. BMI, body mass index.
