Immunohistochemical expression of epithelial mesenchymal transition proteins ZEB1 and E-cadherin in oral leukoplakia and oral squamous cell carcinoma

Table 2 Comparison of zinc-finger E-box-binding homeobox 1 expression in epithelium with respect to intensity, location and percentage scores among the major study groups (oral epithelial dysplasia and oral squamous cell carcinoma) by Kruskal Wallis analysis of variance

ZEB1 expression	Intensity				Location						Percentage of positivity
	0	1	2	Value	0	1	2	3	4	Value	0	1	2	3	Value
OED (n = 30)	0	21	9	-	0	0	22	4	4	-	0	2	10	18	-
OSCC (n = 30)	0	19	11	P = 0.6627	0	0	30	0	0	P = 0.7730	0	1	6	23	P = 0.2643

Intensity: 0: Negative, 1: Mild, 2: Moderate. Location: 0: Absent, 1: Membrane, 2: Cytoplasm + nucleus, 3: Cytoplasm. Percentage: 0: Absent, 1: 1%-25%, 2: 25%-50%, 3: > 50%. OED: Oral epithelial dysplasia; OSCC: Oral squamous cell carcinoma; ZEB1: Zinc-finger E-box-binding homeobox 1.
