Figure 1. Mutual information COVID Severity Score (CSS) relevancy matrix.

(A) Comprehensive matrix of relevancy to CSS of all variables assessed by mutual information algorithm, relevancy scores computed for not-yet selected variables are shown in each column, and variables are ordered to place maximum local scores on the diagonal, yielding a list in decreasing order from the upper left of variable relevancy. Warmer colors indicate higher relevancy, while cooler colors indicate higher redundancy. (B) COVID Severity Score Table with breakdown of categories as well as sample size per category.
