CORRECTIONS

Incorrect dosage: In the article by Merli and Litin entitled “Clinical Pearls in Thrombosis and Anticoagulation,” published in the December 2009 issue of Mayo Clinic Proceedings (Mayo Clin Proc. 2009:84(12):1120-1124), the dosage of enoxaparin was incorrect. The sentence on page 1121, left-hand column, under the heading “Clinical Pearl,” should read as follows: For patients receiving once-daily therapeutic LMWH (200 IU/kg of dalteparin subcutaneously every 24 hours; 1.5 mg/kg of enoxaparin subcutaneously every 24 hours; 175 IU/kg of tinzaparin subcutaneously every 24 hours), the dose 24 hours before surgery should be reduced by 50%.
