  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 low depression rate found may have underpowered the study. Selection of a much less depressive sample than in other studies. Limitation to the first 12 weeks of antiviral treatment.
