Laboratory Risk Indicator for Necrotizing Fasciitis of the Oro-Cervical Region (LRINEC-OC): A Possible Diagnostic Tool for Emergencies of the Oro-Cervical Region

Table 1

Patient background in the OCNF and non-OCNF groups.

Variable	OCNF (n = 26)	Non-OCNF (n = 121)	value
Age (years)	61.9 (22–88)	50 (8–82)	0.173
Gender			0.844
Male (%)	13 (50.0)	57 (47.1)
Female (%)	13 (50.0)	64 (52.9)
Thrombocytopenia			0.075
Platelets < 15 × 10^4 μl	5 (19.2)	9 (7.4)
Malignancy	3 (11.5)	3 (0.02)	0.068
Mortality rate (%)	3 (11.5)	0 (0.0)	0.006

There was no significant difference in age, gender, thrombocytopenia, and coexisting malignant disease between the groups. Seven patients with OCNF treated at our hospital survived, but 3 patients with OCNF in previous reports died, giving a mortality rate of 11.5%. This rate was significantly higher in the OCNF group (, Mann–Whitney U test).
