Table 2.
Obese class III (BMI ≥ 40) vs. Non-obese class III (BMI < 40) infection rates expressed by gender and infection type. Infection rates for SSSI and DSSI are expressed as a percentage (%). Odds ratio (OR) and 95% confidence interval (95% [CI]) are calculated for obese class III versus non-obese class III groups.
