Table 1. Significant differences between mean labelled immune cell counts in the five group comparisons.

Group Comparisons	Group with higher counts	CD4+	CD8+	FOXP3+	MHC-I+	CD68+	CD163+
polypoid vs. nonpolypoid (all sizes)	polypoid		10^-5	10^-7	10^-6	10^-8	10^-7
polypoid vs. nonpolypoid (small lesions only)	polypoid		0.0013	0.0002	0.0001	0.0002	0.001
polypoid vs. nonpolypoid (large lesions only)	polypoid	0.0003	0.0062	0.0003	0.0062	0.0002	0.0002
small vs. large (polypoid lesions only)	large	0.0002
small vs. large (nonpolypoid lesions only)	large	0.0031			0.0166	0.0112

P-values, (Mann-Whitney test) are shown for each difference; statistical significance was set at p-value < 0.05. The direction of mean counts difference is shown for each marker in the five group comparisons.
