In the Review Article entitled “Bleeding in anticoagulated patients with atrial fibrillation: practical considerations” published in the January 2020 issue (Undas A, Drabik L, Potpara T. Pol Arch Intern Med. 2020; 130 (1): 47–58. doi:10.20452/pamw.15136), corrections were needed.

In Table 1 on page 49, the risk factor “CKD with eGFR” for the ATRIA scale should have read “severe CKD.” In the same table, the unit for eGFR was corrected from “mg/dl/1.73 m2” to “ml/min/1.73 m2.” Moreover, the biomarkers included in the ABC-bleeding score enumerated in parentheses should have read “growth differentiation factor-15, high-sensitivity cardiac troponin T, hemoglobin/hematocrit” instead of “differentiation factor-15, high-sensitivity cardiac troponin T, hemoglobin/hematocrit.”

On page 53, the sentence “Although thrombocytopenia does not protect against thromboembolic events, in the landmark phase 3 NOAC trials, patients with AF with platelet count below 90000 to 100000/μl were excluded” was corrected to “Although thrombocytopenia does not protect against thromboembolic events, patients with AF with platelet count below 90000 to 100000/μl were excluded from the landmark phase 3 NOAC trials.”

On page 55, the word “level” was changed to “levels” in the following sentence: “Limited data support the measurement of plasma levels of NOACs in emergencies, before elective procedures, and during long-term exposure.”

On page 56, the word “daily” was added in the title of Table 2, and after the correction, the title reads as follows: “Non­–vitamin K antagonist oral anticoagulants and approved/studied daily doses in stroke prevention in atrial fibrillation (based on Diener et al54 and Steffel et al68).” In the same table, the unit for serum creatinine was corrected from “mmol/l” to “μmol/l”. Moreover, the word “injury” was added in the footnote to the table, and the footnote reads as follows: “Based on clinical and pharmacokinetic data, dose adjustment or NOAC change should be considered if: age ≥75 years, cancer, concomitant antiplatelet drugs or significant drug–drug interactions, frailty/fall risk, chronic kidney disease stage 4, hepatic injury, history of bleeding or predisposition, recent surgery on critical organ and thrombocytopenia.”
