We identified the top 5 mortality-associated topics based on Wilcoxon test on topic proportions between deceased and surviving patients. The color intensity of the heatmap indicates the probability of an ICD codes within a given topic. We selected the top ICD codes whose probability is greater than 0.08. These ICD codes were validated by Fisher’s exact test p values on the eICU and MIMIC-III data, visualized in a scatter plot for the most and least mortality-associated ICD codes. a Mortality-associated topics and ICD codes on eICU. b Mortality-associated topics and ICD codes on MIMIC-III.
