Heatmap demonstrating heterogeneity of the biomarker concentrations among patients at baseline. Patients are ordered across the X-axis based on hierarchical cluster analysis of the percentiles of the biomarker levels, for which the associated intensities are indicated in the greyscale legend at right. The Euclidean distance and Ward’s criterion were used for clustering
