  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
The location of lipodystrophy was not summarized as there was not a place to record the information on the case report form. Too few participants withdrew from treatment to conduct planned analyses of duration to adverse event(s)/discontinuation.
