In an article about the quality of oral anticoagulant management by anticoagulation clinics and by family physicians1 the proportion of patients with high-risk values for international normalized ratio in the family physician group was reported incorrectly. On page 295, column 2, line 18, and in Table 2, row 2, the proportion should be 49% (rather than 40%). The corresponding 95% confidence interval (39% to 59%) was reported correctly.
