Nonunion factors	Odds ratio	p value	95% CI
Percent cortical contact	0.982	0.01	0.969–0.996
Open	2.48	0.01	1.20–5.14
Compartment syndrome	4.13	0.05	1.03–6.59
IIIB fracture	5.17	0.00	2.07–12.89
Chronic disease (Hep/HIV/D)	3.12	0.00	1.22–8.01
Female sex	0.416	0.05	0.17–1.00
ASA score	1.49	0.13	0.886–2.51

CI = confidence interval; Hep = hepatitis C; D = diabetes; ASA = American Society of Anesthesiologists.
