Do patients with low-risk pulmonary embolism discharged early on rivaroxaban require fewer hospitalization days compared to standard of care?

Why is this study important?

The pulmonary embolism (PE) rule-out criteria (PERC) rule was derived to identify patients with a low clinical probability of PE in whom further testing would not be in the patient’s best interest.
