Fig. 4From: Multidimensional associations between nutrient intake and healthy ageing in humansCorrelogram of the strength of correlations (Pearson’s correlation) between intakes of micronutrients (n=3569). Correlations have been clustered hierarchically based on correlation distance (dendrogram). On the basis of this clustering, we grouped micronutrients with highly correlated intakes (> 0.65) for subsequent dimension reduction using principle components analysisBack to article page
