The table shows overdiagnosis (false positives) of life- and limb-threatening injuries on the right. Model statistics represented are Odds Ratios (95% confidence intervals), p values
Referents in the model: for Female Sex was Male, for Penetrating MOI was Blunt, for Polytrauma was Not Polytrauma, for Anesthesiology and Intensive Care base specialty was Emergency Medicine, for Clinician Diagnostic Uncertainty was Clinician Diagnostic Certainty, and for Nightshift was Dayshift
MOI, mechanism of injury; GCS, Glasgow coma scale; SBP, systolic blood pressure; HR, heart rate; Spec, base specialty; Polytrauma, categorical variable meaning ≥ 3 body regions injuried according to abbreviated injury scale (AIS) categories
