Fig. 2

Diet scores for each of the three dietary patterns from the cluster analysis, by age. Estimated trends of diet scores as a function of age, based on data from 5807 women (left panels) and 5092 men (right panels). Four lines are included, where educational level is low(blue)/high (orange) and PAL is low(unbroken lines)/high (dashed lines). For the linear models, the figures include the estimated slopes (\(\hat{\beta }\)), standard deviations (sd) and the p-value evaluating whether the slope is significantly different from 0. For the non-linear models, the figures include the slope estimates at the age of 50 and 80
