To the Editor: In their study comparing fixed-dosed unfractionated heparin with low-molecular-weight heparin for the treatment of VTE, Dr Kearon and colleagues1 concluded that fixed-dose subcutaneous unfractionated heparin was as safe and effective as low-molecular-weight-heparin for the initial treatment of patients with acute VTE. This conclusion was based on the results of a well-designed and conducted noninferiority trial that met prespecified margins of absolute difference for the primary end points.
