Table 1. The semi-quantitative ratios of MIG (CXCL9), IP-10 (CXCL10) and I-TAC (CXCL11) mRNA expression in OLP and NOM tissue compared to 18S / 2:8 competitor mRNA expression.

				P value
Number of samples quantified	CXCL9	12	6
	CXCL10	12	6
	CXCL11	12	6
Ratio of 2:8 18S:chemokine	CXCL9	0.71 (±0.47)	0.144 (±0.24)	* (p = 0.01066395)
	CXCL10	0.49 (±0.23)	0.166 (±0.27)	* (p = 0.02650378)
	CXCL11	0.048 (±0.121793)	0	p = 0.1808416

± standard deviation of the ratios is shown in brackets. Statistical significance is indicated as * = p<0.05.
