Figure 1. Associations of higher genetically predicted Fibroblast Growth Factor 21 (FGF21) concentration with macronutrient intake, anthropometric and cardiometabolic traits, and liver enzymes. Estimates are scaled per additional FGF21-increasing allele of rs838133. The outcomes are in standard deviation units except for fasting glucose (in nmmol/L), fasting insulin (in pmol/L) and lifespan (in years). CI: confidence interval.
