Figure shows boxplots of correlations between metabolites that are part of the same pathway (intra-pathway correlations) compared to correlations between metabolites that belong to different pathways (inter-pathway correlations) in the metformin study (See “Case study” section). Although correlations are not very close to 1. There is an empirically observed correlation signature related to whether metabolites are in the same pathway or not
