| Clinical outcomes | Normal (N=9) | Overweight (N=43) | Obese (N=31) | P value* | Total |
|---|---|---|---|---|---|
| Circumference reduction rate, mean ± SD | 33.97±8.16 | 21.83±10.44 | 24.21±9.35 | 0.005 | 24.04±10.38 |
| Preoperative episodes of infection, mean ± SD | 1.67±1.41 | 3.35±1.02 | 3.32±1.08 | <0.001 | 3.16±1.19 |
| Postoperative episodes of infection, mean ± SD | 0.44±0.72 | 1.21±1.08 | 0.68±0.75 | 0.02 | 0.93±0.97 |
| Infection episode reduction, mean ± SD | 1.22±1.30 | 2.14±1.08 | 2.64±0.98 | 0.003 | 2.23±1.14 |
*, one-way ANOVA evaluated significant differences for circumference reduction rate, pre and postoperative episodes of infection and infection episode reduction means between BMI categories. SD, standard deviation; BMI, body mass index; ANOVA, analysis of variance.
