Dose–response relation between the Nordic diet score and (a) incidence of CVD (RR_{per-diet-score} 0.98 [95% CI 0.97, 0.99], p_linear<0.001, p_{departure-from-linearity}=0.60), (b) CVD mortality (RR_{per-diet-score} 0.94 [95% CI 0.93, 0.96], p_linear<0.001, p_{departure-from-linearity}=0.11), (c) incidence of CHD (RR_{per-diet-score} 0.98 [95% CI 0.96, 0.99], p_linear<0.001, p_{departure-from-linearity}=0.13), (d) incidence of stroke (RR_{per-diet-score} 0.97 [95% CI 0.95, 0.99], p_linear<0.001, p_{departure-from-linearity}=0.97) and (e) incidence of type 2 diabetes (RR_{per-diet-score} 0.97 [95% CI 0.95, 0.99], p_linear<0.001, p_{departure-from-linearity}=1.00). The red lines represent the linear models and the black lines represent the non-linear models. The dotted lines represent the 95% CIs for the non-linear models
