Adjusted odds ratio of selected characteristics associated with the use of advanced diagnostic imaging studies during the emergency department visit (vs. no advanced imaging use), NHAMCS 2009–2014.
Fig 1.
Receiver operating curves for the logistic regression models for different types of advanced diagnostic imaging use (Any ADI, CT, MRI, US, Multiple ADI).
The red point on the curve minimized the Euclidian distance between the ROC curve and the upper left coordinate which defined the best cutoff for this study.
