Factors influencing treatment success of negative pressure wound therapy in patients with postoperative infections after Osteosynthetic fracture fixation

Table 5 Logistic regression models on the outcome parameter “implant survival”

Survival of the implant	Multiple logistic regression model^a
Influencing Parameter	vs.	OR	[95% CI]	p
Bacterial mixture Yes	No	5.0	[1.41–17.92]	0.0126
No detectable germ	No	3.4	[0.82–14.11]	0.0932
Time point of infection late	acute	5.1	[1.93–13.41]	0.0010
Soft tissue damage
Open grade 0–2	Closed	2.6	[0.76–8.78]	0.1262
Open grade 3–4	Closed	10.2	[1.88–55.28]	0.0072

All p-values presented are two-tailed, and p-values lower than 0.05 were considered statistically significant, 95% confidence level (CI)
^aoutcome: implant survival until bony consolidation (yes/no), independent variables: bacterial mixture (dummy coding (yes/no (reference category)/no detectable germ), time of infection (postoperative/late onset), and soft tissue damage (dummy coding (open grade 0–2/open grade 3–4/closed (reference category)
