Table 3 Multiple logistic regression analysis of the odds for accepting the hypothetical treatment (0 = no or uncertain, 1 = yes)

From: Laypersons' understanding of relative risk reductions: Randomised cross-sectional study

Variable Odds ratio (95% CI)
Baseline risk presented (0 = no, 1 = yes) 1.14 0.90–1.44
RRR (reference: RRR = 60)   
RRR = 10 0.60* 0.39–0.90
RRR = 20 1.03 0.69–1.55
RRR = 30 0.91 0.60–1.38
RRR = 40 0.97 0.64–1.46
RRR = 50 1.05 0.69–1.59
Level of education (1–8; 1 = lowest, 8 = highest) 0.93* 0.87–0.99
Annual household income (1–8; 1 = <DKK 100,000, 8 = DKK 799,000+) 1.09* 1.01–1.17
Suffer from hypercholesterolaemia (0 = no, 1 = yes) 1.78* 1.27–2.49
Previously experienced heart attack (0 = no, 1 = yes) 2.38* 1.27–4.47
Respondents finding RRR difficult to understand (0 = no, 1 = yes) 0.33* 0.25–0.44
