1) What implications did the lack of inclusion of clean needles in the prevention package have for trial results?
The study did not provide the clean needles to the study participants yet it is a known standard of prevention among in IDU. I think clean needle is a one factor that effect the results of the study (provide the clean needle may be effect the research question and objective if this study), therefore the wellbeing of subject should be concerned. And ff researcher able to provide complete of prevention package for participant, it the can prove efficacy of study.
2) How can researchers engage stakeholders to better negotiate prevention packages that combine various arrays of options tailored to the needs of diverse subgroups?
Formative research such as CAB meeting can help researchers engage stakeholder in better negotiate prevention package. Researcher should offer many ways and possibility that will do in study and receive comment and suggestion from stakeholder.
