  • Odds ratios and significance levels from logistic regression analyses: multivariate model: study year 1.39 (p<0.001); education 1.42 (p<0.001); interaction between study year and education 0.86 (p<0.001). Less highly educated: one-factor models: study year 1.20 (p<0.001); age group 0.73 (p<0.001); birth cohort 1.34 (p<0.001). Multivariate model: study year 1.23 (p<0.001); age group 0.71 (p<0.001); interaction between study year and age group 1.00 (p = 0.68). More highly educated: one-factor models: study year 1.03 (p = 0.13); age group 0.85 (p<0.001); birth cohort 1.12 (p<0.001). Multivariate model: study year 1.01 (p = 0.76); age group 0.84 (p<0.001); interaction study year and age group 1.01 (p = 0.51).
