Hypothesis

Are non-inferiority and equivalence studies reported with the same rigor as superiority studies?

Conclusion

Non-inferiority conclusions should be based on appropriate confidence interval analysis using predefined criteria.

Supporting Evidence

  • 39% of the studies reported only intent-to-treat analysis for the primary endpoint.
  • 9 out of 18 studies had inconclusive results for non-inferiority.
  • Only 4 studies provided justification for their choice of non-inferiority margin.

Takeaway

This study looked at how well recent AIDS trials showed that new treatments are just as good as existing ones, and found many didn't follow the right rules.

Methodology

The study analyzed 18 recent non-inferiority and equivalence trials in AIDS therapy using standard methodological criteria.

Potential Biases

Potential bias due to lack of blinding and differences in treatment adherence.

Limitations

Only 4 out of 18 studies justified their choice of non-inferiority margin.
