Table 4 Logistic regression showing odds ratio for different clinical presentations as predictors of potentially beneficial ultrasound examination. CI: Confidence Interval, (n = 397), 5 observations left out from fever and 1 left out from abdominal trauma as these groups had no patients with no relevant ultrasound

From: Point-of-care ultrasound induced changes in management of unselected patients in the emergency department - a prospective single-blinded observational trial
