Variable	Adjusted ORs after including all the factors in the model				Adjusted ORs after eliminating the insignificant factors using stepwise regression
	OR	95% CI	P		OR	95% CI	P
Male sex	2.41	1.11, 5.21	0.026		2.30	1.21, 4.38	0.011
Blood glucose (IGT mmol/l)	1.28	1.06, 1.53	0.009		1.26	1.06, 1.50	0.009
BMI (≥25 kg/m2)	1.87	1.00, 3.50	0.050		2.25	1.26, 4.02	0.006

The OR for blood glucose was continuous and calculated for 1 unit.
