Does a simple quantitative decision rule improve the diagnosis or exclusion of pulmonary embolism compared to physician assessment in symptomatic patients with a non-high probability ventilation-perfusion scan?
A simple 5-variable decision rule outperformed physician assessment in diagnosing or excluding pulmonary embolism in patients with non-high probability V/Q scans, though it requires prospective validation.
