Table 2. Association between Fusobacterium abundance and colorectal adenomas.

Categories*	Case (n = 48)	Control (n = 67)	OR (95% CI)**
Tertile 1	8	23	Reference
Tertile 2	12	22	1.57 (0.54–4.57)
Tertile 3	28	22	3.66 (1.37–9.74)

^*The abundance of Fusobacterium among control subjects were used to generate tertile cut-off. The lowest tertile of Fusobacterium abundance was considered as the reference.

^**Odds ratio and 95% confidence interval.

Compared to subjects with a low copy number, subjects with high abundance of Fusobacterium are more likely to be adenoma cases than controls.
