Intro: This 2008 study was the second large validation study of the Pulmonary Embolism Rule Out Criteria (PERC) rule. The researchers aimed to test the hypothesis that follows: patients who presented with signs and symptoms of PE but were estimated to be low risk by clinician gestalt (<15% pretest probability), in addition to being PERC negative, would have a <2% risk of VTE. Less than 2% was determined to be the point of equipose, where the dangers of workup for PE in this g
