Randomised Controlled Trials: What the Surgeon Needs to Know

  • Chapter
Key Topics in Surgical Research and Methodology

Abstract

In this chapter, we discuss some of the methodological issues in the design and conduct of clinical trials of surgical rocedures. The opinion of experts in trial design, management and analysis should be sought at an early stage of a surgical clinical trial programme, recognising that other study designs may also be important including the prospective protocol-driven registry and the case control study.
