Spearman Rank Correlation of the signal values (A, C, E) between sample microarrays and Spearman Rank Correlation of the detection p values (B, D, F) between sample microarrays for plasma (A,B), vitreous (C,D), and aqueous (E,F). The heatmap contains a pairwise comparison of the signal values from all the selected sample microarray files, where the Spearman r2 values have been converted into a pseudocolor scale.
