  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
The study was terminated early and thus only a fraction of the planned number of patients were randomized and many did not complete the study. As a consequence the possibility of interpreting efficacy over an 8 week period is considerably reduced.
