		B	SE	Wald	df	p-value	OR	95% CI for OR

Glycaemic Index Step 1a	Glycaemic Index less than 40	0.665	0.386	2.975	1	0.085	1.944	0.913	4.140
	Constant	0.000	0.254	0.000	1	1.000	1.000
Glycaemic Load Step 1b	Glycaemic load categories			6.037	2	0.049
	Glycaemic load less than 10	0.470	0.575	0.668	1	0.414	1.600	0.518	4.938
	Glycaemic load 10–20	-0.649	0.497	1.705	1	0.192	0.523	0.197	1.384
	Constant	0.511	0.422	1.468	1	0.226	1.667

^aVariable(s) entered on step 1: Glycaemic index greater than 40

^bVariable(s) entered on step 1: Glycaemic load greater than 20 was considered as a reference value
