Odds ratio (OR) and 95 % confidence interval (95 % CI) of colorectal cancer and adenoma in relation to food groups diversity

Food group diversity	Colorectal Cancer OR (95 % CI)a	Colorectal Adenoma OR (95 % CI)a
Grains diversity score	2·96 (1·05–8·32)	0·71 (0·25–1·93)
Vegetable diversity score	0·31 (0·16–0·62)	0·41 (0·21–0·78)
Fruit diversity score	0·37 (0·23–0·61)	0·58 (0·36–0·93)
Dairy diversity score	0·72 (0·49–1·06)	0·56 (0·37–0·83)
Meat diversity score	1·29 (0·73–2·27)	1·44 (0·84–2·46)

Logistic regression was performed to obtain the odds ratio (95 % CI) of colorectal cancer and adenoma.
