Relatedness of survival predictors. To identify predictor relatedness, a correlation matrix (Pearson correlation) of markers associated with 28-day survival was generated and ordered via hierarchical clustering (non-significant correlations are plotted in white). We observed two clusters: one cluster with highly related markers such as renal markers and newer biomarkers (generalised predictors in grey); the other cluster consisted of a diverse set of predictors with only a minor association to other markers (specialised predictors in black)
