Prevalence of unrecognized scar (a) and unrecognized MI (b) in relation to BMI groups. BMI groups are expressed as quintiles of the study population. The red line separates patients with normal weight (BMI <25 kg/m2) from patients with obese (BMI ≥25 kg/m2). The dashed blue line depicts the cut-off (29.5 kg/m2), which separates the mildly obese from the severe obese patients. Odds ratios for UScar and UMI for severe obese versus mild obese are shown, unadjusted and adjusted for Framingham Risk Score not including weight.
