Objective:

To examine whether hypertension risk stratification modifies the effect of anticoagulation compared to antiplatelet therapy in patients with cryptogenic stroke.

Key Findings:
  • 25% to 30% of ischemic strokes are cryptogenic, likely involving multiple mechanisms.
  • Anticoagulation has not shown superiority over antiplatelet therapy in trials for embolic stroke of undetermined source.
  • Hypertension-related cerebrovascular disease may obscure the benefits of anticoagulation.
Interpretation:

Remove this section as it contains unsupported conclusions.

Limitations:
  • The analysis was not prespecified in the trial protocol.
  • Results may be influenced by the inclusion of patients with severe hypertension.
Conclusion:

Revise to eliminate speculative language and focus on findings directly supported by the study.
