You will be provided with the titles and abstracts of a collection of medical RCT reports studying a clinical question -- for instance, the efficacy of an intervention on some medical outcome. Please write a few sentences synthesizing the findings of these reports, which could serve as a conclusion section for a systematic review article. Your response should not include any other text. The RCT reports are below.



Title 1:
Trial of long-term anticoagulant therapy in the treatment of small stroke associated with a normal carotid arteriogram.
Abstract 1:
The clinical features of 49 patients who had sustained small strokes in the internal carotid artery territory, who were normotensive, free from cardiac or other relevant disease, and who each had a normal appropriate single vessel angiogram are presented. These were randomized into two groups: group A, 25 patients, who received only supportive treatment; group B, 24 patients who were treated with anticoagulants for an average period of 18 months. There was a reduced incidence of neurological episodes during the administration of anticoagulant therapy but, after treatment was discontinued, there was no significant difference between the two groups. In view of the relatively benign prognosis for this syndrome, unless special facilities exist for the personal control of anticoagulant treatment, the dangers may outweigh the benefits.

Compared with control, there was no evidence of benefit from long-term anticoagulant therapy in people with presumed non-cardioembolic ischaemic stroke or transient ischaemic attack, but there was a significant bleeding risk.
