Model including only those variables identified in the PECARN retrospective case-control study.
Model created by using stepwise forward variable selection.
Estimated by applying model to entire cohort, with the presence of any risk factor indicating need for imaging, and all no indicating imaging unneeded.
Estimated by applying the model to those that had the CT in the cohort, with the presence of any risk factor indicating need for the CT and absence of all risk factors indicating CT unneeded.
