Impact of Missing Data on Identifying Risk Factors for Postoperative Complications in Hand Surgery.

ABSTRACT:

Background

The mismanagement of missing data in large clinical databases may lead to inaccurate findings. The purpose of this study was to demonstrate the effects of missing data on hand surgery research findings using an analysis of postoperative morbidity in patients undergoing hospital-based hand surgery.
