  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 rate of maternal highly active antiretroviral therapy use was higher than expected in our study. Thus there were fewer infant infections which decreased the power to detect differences in HIV transmission risks between study groups.
