Table 2.

Comparison of the number of cases showing high and low protein expression of Skp2 and p27 in oral epithelial dysplasias and carcinomas

	Low Skp2	High Skp2
Low p27	36	11
High p27	26	0

For both markers, the cut-off for high expression was defined as >20% nuclei positive. P = 0.013, Fisher's exact test.
