CRP and Sepsis: The fact that, from a set of medical parameters (Table A3), sCD163 was iteratively chosen to be a part of the classification model (logistic regression) shows that the knowledge about the values of sCD163 concentration may potentially be used as an auxiliary feature in models predicting survival status, along with parameters which have been used in assessment of patients’ condition and sepsis severity (e.g., APACHE II and CRP, as featured in Table 4: model 2).
