(20 cards)
What is the definition of Evidence-Based Medicine (EBM)?
EBM is the integration of clinical expertise with the best available clinical evidence from systematic research.
Who first defined EBM in 1996?
David Sackett and colleagues.
What are the three key components of EBM?
Best research evidence, clinical expertise, and patient values/preferences.
What does EBM aim to support in clinical care?
EBM supports decision-making in clinical care.
Why was EBM introduced into modern medical practice?
To shift away from experience-based and tradition-based practice.
Give an example of a clinical question EBM can help answer.
Can progesterone prevent preterm labour?
What is the first step in practising EBM?
Asking a focused clinical question and searching for the best available evidence.
What is a Randomised Controlled Trial (RCT)?
A study where participants are randomly allocated to treatment or control groups.
What makes RCTs a gold standard in research?
Randomisation reduces bias and balances groups for comparison.
What is a systematic review?
A structured summary of all available studies on a specific topic.
What is a meta-analysis?
A statistical technique to combine results from multiple studies.
Can a systematic review exist without a meta-analysis?
Yes — systematic reviews may not always include meta-analysis.
What is the benefit of a meta-analysis?
Increases statistical power and helps in drawing broader conclusions.
What is the Cochrane Library?

Why is the Cochrane Library considered the gold standard?
It applies rigorous methodology, exhaustive literature search, and expert collaboration.
What is the CDSR?
Cochrane Database of Systematic Reviews.
What kind of questions do Cochrane reviews address?
Practical clinical questions like: “Is magnesium sulfate effective in preeclampsia?”
What is a forest plot?
A graphical summary of the results of a meta-analysis.
Name two other EBM resources besides Cochrane.
PubMed, ACP Journal Club.
