Scatterplot of DA model based on systemic concentration of interleukins and calprotectin in salmonellosis patients and controls. The number of variables in the model—4 (IL-17, IL-1β, IL-10, and calprotectin) and grouping consists of three groups. Roots 1 and 2—discriminant functions 1 and 2 (1st and 2nd canonical roots). Group centroid positions are numbered: (a) 1—healthy control subjects, 2—patients with acute S. Typhimurium infection, and 3—patients with acute S. Enteritidis infection; (b) 1—healthy control subjects, 2—patients with acute S. Enteritidis infection, and 3—patients in the convalescent state following the previous acute S. Enteritidis infection.
