  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
Unable to evaluate the effect of valacyclovir on MTCT or on change in HIV-1 RNA among women who were eligible for HAART. Underpowered to detect association between treatment and mother to child HIV transmission.
