As a way to confirm the validity of our results for feature selection, we note that age [8,11,12,13], CHD [4,11,12], CRP [12,13], neutrophil [4,13] and LDH [7] were also proven to be statistically significant features to predict the Mortality outcome, while age [14], CRP and LDH [3,5,9,14] (among many others) were found to be statistically significant for the Severity outcome. The gene discussed is CRP; the disease is coronary artery disorder.
