  Limitations and Caveats
  Hide Limitations and Caveats

Limitations of the study, such as early termination leading to small numbers of participants analyzed and technical problems with measurement leading to unreliable or uninterpretable data
Limited number enrolled. Study was designed to demonstrate feasibility for a pivotal trial, but small enrollment limits the final conclusions that can be drawn from a simple 'time to first atrial fibrillation recurrence.'
