    Discrepancy between overall ATE frequency stated in abstract vs main text
    • Prabal Mittal, Haematology Clinical research fellow University College London Hospital

    Thank you to the authors for this important and detailed analysis. I write to simply draw attention to a discrepancy, unless I am mistaken, between the ATE frequency rates stated in the abstract and those in the main text.

    Abstract: "The frequency rates of overall ATE, acute coronary syndrome, stroke and other ATE were 3.9% (95% CI 2.0% to to 3.0%, I2=96%; 16 studies; 7939 patients), 1.6% (95% CI 1.0% to 2.2%, I2=93%; 27 studies; 40 597 patients) and 0.9% (95% CI 0.5% to 1.5%, I2=84%; 17 studies; 20 139 patients), respectively".

    Main text: "The weighted frequency of ATE was 4.0% (95%CI 2.0% to 6.5%, I2 =95%; 19 studies; 8249 patients), including myocardial
    infarction/acute coronary syndrome (1.1%, 95%CI 0.2% to 3.0%, I2=96%; 16 studies; 7939 patients), ischaemic stroke (1.6%, 95%CI 1.0% to 2.2%, I2 =93%; 27 studies; 40597 patients) and other ATE (0.9%, 95%CI 0.5% to 1.5%; I2
    =84%; 17 studies; 20139 patients)
