CHARACTERISTICS OF THE EVIDENCE
One randomized controlled trial met the criteria and was included in the review. Fifty participants with a mean age of 55.25 ± 12.37 years who were treated with subcutaneous heparin (including low-molecular-weight and unfractionated heparin) were included in the study. Owing to the nature of the intervention it was not possible to blind the participants. The overall quality of the evidence was moderate.
