Table 4

Multivariable stepwise logistic regression modeling for risk factors in association with infection.

	Regression coefficient ()	Odds ratio (OR)	95% confidence interval (CI)	value

The following risk factors were also included in the stepwise logistic regression modeling selection: antibiotic use, diabetes, gender, prior surgery, surgeon, large surface area, BMI > 25 kg/m² (yes/no), surgery age, surgery age > 50 years (yes/no), and mammoplasty.
