Table 2 Proportions with the factor (at pretest and posttest), point estimates and confidence intervals (95% CI) for the ratio between proportions and the exact McNemar significance p-value, criterion for positivity in the footnote

	Pretest	Posttest	Ratio post/pre (95% CI)	McNemar exact p-value
	Proportion with factor		Ratio post/pre (95% CI)	McNemar exact p-value
Physical activity (PA)	0.42	0.61	1.46 (1.32 - 1.62)	0.0000
Cigarette smoking (CS)	0.40	0.34	0.84 (0.78 - 0.92)	0.0000
Alcohol drinking (AD)	0.45	0.39	0.86 (0.79 - 0.94)	0.0017
Systolic blood pressure (SBP)	0.46	0.38	0.83 (0.74 - 0.92)	0.0009
Blood cholesterol (BC)	0.68	0.58	0.85 (0.78 - 0.93)	0.0004
Cardiovascular risk (CR)	1.00	0.76	0.76 (0.71 - 0.80)	0.0000

Criterion for positivity: physical activity for ≥150 minutes/week (PA); current smoker (CS); regular drinker (AD); systolic blood pressure >140 mmHg (SBP); blood cholesterol >200 mg/dl (BC); cardiovascular risk >5% (CR).
