A graphic framework for teaching critical appraisal of randomised controlled trials.
Abstract: Students of evidence-based medicine often try unsuccessfully to commit to memory a particular critical appraisal framework (often lengthy), or they have to depend on pocket cards and are lost without them. We have described a pedagogic aid: a flow diagram of an RCT, which has been developed over years of teaching residents. This diagram focuses on the steps in an RCT, and by drawing arrows, it highlights the biases possible at each step. This diagram serves as a framework on which the list of critical appraisal questions can be hung and is easy to remember.

The study presents a teaching tool in the form of a flowchart for understanding randomized controlled trials (RCTs). This new method simplifies the study of evidence-based medicine and aids in the easy identification of potential biases at each step of an RCT.
Teaching Tool Design
- This research introduces a pedagogical tool which aims to assist students of evidence-based medicine in understanding and analyzing Randomized Controlled Trials (RCTs).
- The teaching tool is a flow diagram representing the steps involved in an RCT. The diagram has been developed over several years of teaching resident students.
Function and Usage of the Teaching Tool
- Your tool doesn’t just present the steps involved but, by utilizing arrows, it can highlight potential biases that might occur at each stage of the trial.
- It can replace traditional memory-based methods or dependence on pocket cards for understanding and critically appraising RCTs.
Benefits of the Diagram
- The graphical representation of an RCT provides a visual structure that aids students in remembering significant aspects of these trials.
- For each step in the flow diagram, students can “hang” or attach corresponding critical appraisal questions. This can help in creating a systematic approach towards verifying the validity and quality of an RCT.
- In essence, this teaching tool attempts to amalgamate the process steps and critical analysis of RCTs into an easily understandable and memorizable format.
