Factors with a significant association with OCNF in multivariate analysis (logistic regression analysis).

Variable	Logistic
	β	SE	p value	Odds ratio	95% CI
CRP	3.530	0.916	≤0.001	34.129	5.667	205.519
WBC	2.031	0.882	0.021	7.623	1.353	42.951
Cr	3.535	1.274	0.006	34.294	2.826	416.165
Skin flare area
Cervical region	1.897	0.913	0.038	6.665	1.113	39.927
Precordial region	2.597	1.310	0.048	13.422	1.029	175.073

CRP, WBC, Cr, and skin flare in the cervical and precordial regions were extracted as independent factors () and evaluated as predictors of OCNF. The multivariate-adjusted odds ratios were high for CRP (34.13, 95% confidence interval (CI) 5.67–205.52) and Cr (34.30,95% CI 2.83–416.17), indicating that these variables were the most important predictive factors. β: regression coefficient; SE: standard error.
