Median scores and mean ranks of COX-2 expression according to group

Group	Median score*	Mean score
AOM + basal diet (G1)	6.00a	324.16
AOM + basal diet + 2.5 g/kg of GBR (G2)	5.00b	241.72
AOM + basal diet + 5 g/kg of GBR (G3)	4.00c	182.25
AOM + basal diet +10 g/kg of GBR (G4)	4.00c	170.04
Basal diet alone (G5)	3.00d	54.15

*Median scores with different superscript are significantly different at p < 0.05 (Mann-Whitney U-test).
