Table 1. The ten groups within which N-glycan abundances were analyzed in this study.

Number	Group	Size
1	Right-sided CRC vs. left-sided CRC	18 vs. 17
2	Right-sided CRC vs. left-sided CRC, stage II samples only	9 vs. 9
3	Right-sided CRC vs. left-sided CRC, stage III samples only	9 vs. 8
4	Stage II vs. III CRC, all samples	18 vs. 17
5	Stage II vs. III CRC, right-sided samples only	9 vs. 9
6	Stage II vs. III CRC, left-sided samples only	9 vs. 8
7	Healthy colon tissue, right vs. left	5 vs. 5
8	Right colon, healthy tissue vs. CRC	5 vs. 18
9	Left colon, healthy tissue vs. CRC	5 vs. 17
10	Healthy colon tissue vs. CRC, all samples	10 vs. 35

For each group, relative N-glycan abundance was analyzed separately for both neutral and acidic N-glycans. N-glycan abundance was analyzed for the proposed monosaccharide compositions and, separately, for the proposed structural classes of glycans.
