Tumour marker correlation structure and missingness. (a) A heatmap representing pairwise Pearson correlation statistics among the various immunohistochemistry (IHC) intensity score tumour markers. (b) A heatmap representing pairwise Pearson correlation statistics among the various IHC proportion score tumour markers. (c) Pearson correlation statistics between IHC intensity and proportion scores for those proteins where both were measured. (d) Proportion of missing values for each tumour marker in the analysis population.
