Principal component analysis (PCA) plot of the two clusters. A PCA plot is a 2D representation of high-dimensional data. In this case, the dimensions consist in measurements of serum insulin at different time points of the oral glucose test (OGT). Data-points that are close show a similar insulin response during the OGT (cluster 1—dark blue points; cluster 2—light blue triangles)
