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

From: A worksite intervention to reduce the cardiovascular risk: proposal of a study design easy to integrate within Italian organization of occupational health surveillance

  Pretest Posttest Ratio post/pre (95% CI) McNemar exact p-value
Proportion with factor
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
  1. 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).
