A comparison of matched and aggregated group outcomes data for evaluating continuing education of hematology and oncology health care professionals.

Introduction: Capturing educational outcomes from health care professionals is often challenging.

To address the agreement between aggregate and matched outcomes, a preliminary analysis was conducted.
