Regression analysis of the self-reported hygienic practices during food handling dependent on the sink placement either inside or outside the kitchen.

	Model	Sink placement	β (SE)	BCa (95% CI)	OR (95% CI)	p
How likely is it that you would clean your hands immediately after touching raw chicken?*	1	Inside	0a		1
		Outside	−0.64 (0.03)	−0.32; −0.89	0.52 (0.44; 0.61)	0.00**
After cutting chicken, how likely is it that you will re-use the same cutting board for vegetables, salads or fruit?*	2	Inside	0a		1
		Outside	0.37 (0.08)	0.19; 0.54	1.5 (1.23; 1.71)	0.00**
After cutting chicken, how likely is it that you will re-use the same knife (without washing it) for vegetables, salads or fruit?*	3	Inside	0a		1
		Outside	0.56 (0.08)	0.25; 0.86	1.8 (1.48; 2.07)	0.00**

β = regression coefficient; SE = standard error; BCa (95% CI) = Bias-corrected accelerated (95% confidence interval) using the bootstrapping technique (1000 iterations); OR (95% C.I.) = odds ratio (95% confidence interval); a = reference value; *N = 7866 valid answers; **p < 0.01.
