Unsupervised clustering of normal and DFU subjects based upon analyte levels. Unsupervised clustering of normal () and DFU () subjects with the dendrogram scaled to represent the distance between each branch. Normalized signal intensities ( transformed and row adjustment) are visualized as a color spectrum. Blue color indicates low expression and red color indicates high expression of the detected markers.
