a. Pearson correlations between baseline values and postprandial prediction measures of 980 participants from the UK cohort. b. Heritability of postprandial responses (the ACE model was fitted on log-scaled postprandial responses for triglyceride, glucose, insulin and C-peptide) in 183 MZ and 47 DZ twin pairs. A; additive genetic component, C; shared environmental component, E; individual environmental component. c. SNP associations with postprandial measures focusing on SNPs identified in published postprandial trait GWAS17–21 (n = 241; * p<0.05, *** p<0.001, using two-sided chi-squared test).
