Analysis of subjects treated with therapeutic antibiotics as a function of diagnosis, evaluation method, and cohort: logistic regression models. a Discrimination of SIRS patients who were treated vs. not treated with therapeutic antibiotics, using a five-variable logistic model (y = − 17.8210 − 0.0200 * MAP.Min + 0.0128 * HR.Max + 0.4540 * Temp.Max + 0.0906 * Hospital.LoS + 0.2472 * N.SIRS). The model gave AUC 0.72 (95% CI 0.63–0.81) in ROC curve analysis. b Discrimination of SIRS patients who were treated vs. not treated with therapeutic antibiotics using a four-variable logistic model (y = − 16.5106 - 0.0239 * MAP.Min + 0.0125 * HR.Max + 0.4372 * Temp.Max + 0.2386 * N.SIRS). The model gave AUC 0.71 (95% CI 0.62–0.80) in ROC curve analysis. Additional file 7 provides further details. Abbreviations: AUC, area under curve; Hospital.LoS, length of stay in hospital; HR.Max, maximum heart rate; MAP.Min, minimum mean arterial blood pressure; N.SIRS, number of SIRS criteria met; ROC, receiver operating characteristic curve; Temp.Max, maximum core temperature; WBC.Max, maximum white blood cell count; WBC.Min, minimum white blood cell count
