Hypothesis
Location may negatively impact on trial quality in regions where resources are scarce.
Conclusion
African trials report higher methodological quality than North American trials.
Supporting Evidence
- African trials were three times more likely to report adequate allocation concealment.
- African trials were twice as likely to report adequate generation of the sequence.
- Most African trials are externally funded, possibly leading to stricter reporting standards.
Takeaway
This study found that trials for HIV/AIDS in Africa are often better reported than those in North America, possibly due to stricter funding requirements.
Methodology
The study compared the methodological quality of HIV/AIDS RCTs in Africa and North America using logistic regression analyses.
Potential Biases
Potential measurement bias may have been introduced due to reliance on reported data.
Limitations
The study's findings may not be causally related and are dependent on the quality of reporting.
Participant Demographics
Trials conducted in 18 countries in sub-Saharan Africa and North America.
