With respect to our article titled "The Incidence of Recurrent Venous Thromboembolism After Treatment With Vitamin K Antagonists in Relation to Time Since First Event: A Meta-analysis,"1 we want to state the following: There appeared to be a small error in our explanation for observed heterogeneity in the first period after discontinuation of treatment in the group of studies in which patients were treated for 3 months. We assumed that this heterogeneity was due to the relatively high number of patients with cancer included in one study (Kearon et al2 [reference 106 in our study]). However, the authors of that study notified us that in their study no patients with cancer were included.
