There is NOT an agreement between Principal Investigators and the Sponsor (or its agents) that restricts the PI's rights to discuss or publish trial results after the trial is completed.


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
Intervention was stopped at 12 months, transition phase did not ensure that participants developed a set of adherence strategies to replace DOT-ART. Low incidence of AIDS-defining illness and death limit our ability to make final conclusions
