  Serious Adverse Events

  Other Adverse Events

  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
Since this was a proof of concept study evaluating safety and tolerability of the intervention in this population, it was not powered to achieve statistical significance in changes observed from baseline to week 24 in any of the endpoints.
