Patients were evaluated 6 to 36 months after venography confirmed deep vein thrombosis in the lower extremity.
Clinical symptoms:
(1) pain
(2) cramps
(3) pruritis
(4) paresthesia
Clinical objective signs:
(1) pretibial edema
(2) induration of the skin
(3) hyperpigmentation
(4) new venous ectasia
(5) redness
NOTE: The use of signs and symptoms in the paper are reversed, probably as a result of the translation into English.

Performance:
• The kappa values for interobserver agreement for deriving scores was 0.77 to 0.80.
• The kappa value for assigning disease severity was 0.75 (95% CI 0.51 – 0.99).
