<p>The bars sharing the same letter are not statistically significant (P ≥ 0.05) according to a paired t-test. The term ‘glucose - liver’ on the x-axis represents the prediction of the glucose concentration using the gene expression levels in the liver. The white, gray, and black bars correspond to the accuracy of prediction using the SNP genotype, gene expression level, and both SNP genotype and gene expression level, respectively.</p
