To evaluate the performance of the 25 and 22 predictive genes (unfiltered vs filtered genes of EIF1AY, APOBEC3B, and GUSBP3) in classifying samples from the two patient groups, E. coli-induced sepsis vs. S. aureus-induced sepsis, we conducted a two-group classification analysis using logistic regression algorithm. The gene discussed is EIF1AY; the disease is Sepsis.
