  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 reason for early termination: Study was terminated after the primary efficacy analysis at Week 24 did not demonstrate non-inferiority of MK0518 versus KALETRA™.
