Effect of anticoagulant therapy for 6 weeks vs 3 months on recurrence and bleeding events in patients younger than 21 years of age with provoked venous thromboembolism. The Kids-DOTT randomized clinical trial.

Goldenberg NA, Kittelson JM, Abshire TC, Bonaca M, Casella JF, Dale RA et al, for the Kids-DOTT Trial investigators and the ATLAS Group.
JAMA 2022; 327: 129-137.

Comment: Very low recurrence rates, but six weeks of anticoagulation seems reasonable.
