Episode 25: The Proportional Odds Assumption in Clinical Trials
In this QCast episode, Jullia and Tom unpack the proportional odds assumption in ordinal logistic regression, explaining what it means in practice, why it matters for ordinal endpoints in clinical trials, and how to diagnose and handle violations without losing the value of ordered scales.
Key Takeaways
- Understand that proportional odds implies a single treatment effect across all cut points of an ordered endpoint, enabling an efficient summary of benefit.
- Examine outcome distributions, use formal tests, and compare treatment effects across thresholds to assess whether the assumption is reasonable.
- Plan for alternatives such as partial proportional odds or more flexible models, and document the rationale so methods and interpretations remain transparent to clinicians and regulators.
