Summary of the Proposed Research:
Stroke is a life‐threatening medical condition in which brain tissue is damaged. Ischemic stroke is caused by a clot blocking the blood supply to part of the brain. There are ischemic strokes without a known origin of the clot, called cryptogenic. Because approximately 1 in 4 stroke survivors will likely have another stroke event, finding the cause of the stroke helps clinicians to select the most effective and safe pharmacological treatment to lower the likelihood of another cerebrovascular event (secondary prevention). Antithrombotic are blood thinning medicines that prevent clots from forming and growing and therefore are used to prevent the recurrence of stroke. There are two classes of antithrombotic agents, anticoagulants that slow down clotting and antiplatelets that prevent platelets from clumping. In the case of cryptogenic stroke, there is uncertainty about the best approach.
We aim to conduct a systematic review, a research project to collect, extract and interpret data from published studies on the topic, with network meta-analysis, a statistical technique that allows the quantitative comparisons of the effects interventions (medicines) that were not investigated by the same study.
