Need for Trial Registration and Reporting
� Clinical trials give valuable evidence on health
interventions
� They give extensive media coverage of several
cases of selective reporting of results
� Help ensure a full unbiased public record on
safety and effectiveness
� Strengthen public trust, avoid drop in
participant enrollment

Which Trials Must Register?
� Registration of all interventional trials is a scientific, ethical, and moral responsibility
� Any research study that prospectively assigns humans or groups of humans to health-related interventions
� Includes Phase I to Phase IV trials
