Model A includes confounders and educational level.
↵4-150 95% confidence intervals do not include 1. OR, odds ratio, adjusted for gender, age, and physical activity in 1991. %, % reduction in odds ratio = (OR model A − OR model A + predictor)/(OR model A − 1).
↵4-151 Reduction in deviance due to inclusion of education in the model.
↵4-152 ΔRD = (reduction in deviance due to education of model A) − (reduction in deviance due to education of model A + predictor).
↵4-153 Percentage explained of reduction in deviance due to inclusion of education in model A = (ΔRD/RD education of model A) × 100%.
