Figure 3From: Statistical hypothesis testing of factor loading in principal component analysis and its application to metabolite set enrichment analysisResults of PCA in a comparative study of db / db mice treated with and without pioglitazone. (A) Scores plot of PC1 and PC2. Symbols: (○) diabetic model mice (db/db mice) without pioglitazone; (●) db/db mice administered pioglitazone. (B) Factor loading plot for PC1. Metabolites are sorted in ascending order of the value for factor loading. The dotted line shows the significance level at p < 0.05.Back to article page
