Generating Reliable Clinical Information – Barriers and Biases in Cohort Studies and Randomized Controlled Trials
Organized by the ORS Clinical Research Forum Committee
The Clinical Research Forum will focus on the utility of cohort studies and challenges of randomized trials. Speakers will highlight key elements of cohort studies, provide a reference standard in designing observational studies and clarify the difference between cohort studies and registry data. The Forum will continue with an in-depth discussion of the many sources of bias in randomized trials. Finally, a lively debate will weigh the timeliness and importance vs. the drawbacks and challenges of Open Access Data in clinical research. Overall, the Forum will provide an informative, up-to-date and interactive discussion on clinical research in Orthopaedic Surgery.
