Clinical variables were derived and validated in two independent cohorts of patients suspected of having a pulmonary embolism (PE). There were 965 patients in the derivation group and 756 in the validation group.
Univariate analysis identified 10 variables statistically associated with PE, eight of which remained significant in a multivariate analysis. Each variable was assigned points based on the regression coefficient: age 
65 years (1 point), previous deep venous thrombosis or PE (3 points), surgery or fracture within 1 month (2 points), active malignancy (2 points), unilateral lower limb pain (3 points), haemoptysis (2 points), heart rate 75–94/min (3 points) or 95/min (5 points), and pain on lower limb venous palpation with unilateral oedema (4 points).
