Analysis of the relationship between risk factors and flap loss (complete or partial) in patients undergoing bilateral breast reconstruction with TRAM, DIEAP or SIEA flaps.
| Variable | Complete or partial flap loss | |
|---|---|---|
| P | β coefficient (CI) | |
| Age (years) | 0.751 | 0.001 (−0.002, 0.003) |
| BMI (kg/m2) | 0.002 | 0.014 (0.005, 0.024) |
| Smoking (0=no, 1=yes) | 0.844 | 0.051 (−0.069, 0.171) |
| Diabetic (0=no, 1=yes) | 0.662 | −0.088 (−0.489, 0.312) |
| Radiotherapy (0=no, 1=yes) | 0.189 | −0.047 (−0.119, 0.0237) |
Analysis of variance p-values for the null hypothesis of no relationship between risk factors and complete or partial flap loss are displayed. Regression coefficients (β coefficient) and their 95% Confidence Intervals (CI) for the risk factors are also given. The coefficient of determination (R2) for this analysis is 10.0%. BMI, Body mass index. Smoking refers to current active smoking.
