The main clinical scoring models for predicting the pre-test probability of pulmonary embolism. Well's score, revised Geneva and simplified revised Geneva are scoring systems for assessment of suspected PE [24–26].

Well's Score		Revised and simplified revised Geneva scores
Clinical characteristics	Score	Clinical characteristics	Revised score	Simplified score
Haemoptysis	+1	Age >65 years	+1	+1
Cancer	+1	Active malignant condition	+2	+1
Previous pulmonary embolism or deep venous thrombosis	+1.5	Surgery or fracture within 1 month	+2	+1
		Haemoptysis	+2	+1
Heart rate >100/min	+1.5	Previous deep vein thrombosis or pulmonary embolism	+3	+1
Recent surgery or immobilisation	+1.5
Clinical signs of deep venous thrombosis	+3	Unilateral lower-limb pain	+3	+1
		Heart rate 75–94/min	+3	+1
Alternative diagnosis less likely than that of pulmonary embolism	+3	Pain on lower-limp deep venous palpation and unilateral oedema	+4	+1
		Heart rate >94/min	+5	+1
Clinical probability		Clinical probability
Low	<2	Low	0–3	0-1
Intermediate	2–6	Intermediate	4–10	2–4
High	>6	High	>10	≥5
