Task: Answer Verification
Input (English): Question: Is serum lipoprotein ( a ) levels in patients with first unprovoked venous thromboembolism associated with subsequent risk of recurrent VTE?
Answer: Elevated serum Lp(a) does not appear to be associated with recurrent VTE in patients with history of first unprovoked VTE and may not play a role in identifying patients with unprovoked VTE at high risk of recurrence. There was no optimal predictive threshold for the overall population or for sex sub-groups and Lp(a)>or=0.3 g/L was not a significant predictor of recurrent VTE.
Output (English): no
