If we select variables that appear at least 50% of the time, our reduced model would include: Age, BE (abnormal), CRP (abnormal), eGFT (abnormal), HB (severe), PLT (mild, moderate), Lymphocytes (Severe), Neutrophils (Mild, Severe), NLR (Severe), APTT (mild, moderate), 0xygen (abnormal), PT (abnormal), blood pH (abnormal), Urea (abnormal), and positive viral, respiratory, and blood culture co-infections. The gene discussed is CRP; the disease is coinfection.
