Extended Data Fig. 2: A Bayesian Network model of the impact of diet on serum metabolites and lifespan and peak body weight at 500 days age.
From: Gene-by-environment modulation of lifespan and weight gain in the murine BXD family

Edge weights in this network are the weighted fraction of best 1000 Bayesian models that have the same edge and polarity. A value of 1.0 means every one of 1000 “top-ranked models” has this edge. The upper 6 nodes are serum metabolites, and lifespan and body weight at 500 days age are the final outcomes.
