Abstract
BACKGROUND: Subgroup analyses are relatively easy to perform but can be difficult to interpret. Credibility is often low, whereas the risk of over-interpretation is high. ICEMAN is a structured approach generated through expert consensus and provides eight items for judging the credibility of subgroup effects identified in a meta-analysis.
OBJECTIVES: Learn how to apply ICEMAN to an apparent subgroup effect and, if credible, how to design a corresponding GRADE summary of findings table.
DESCRIPTION: Participants will apply ICEMAN to examples from the literature. We will discuss, for each item, conceptual and practical challenges.
The workshop does not include statistical exercises; the focus is on the interpretation and reporting of subgroup effects.
Participants should bring their laptop, if available, and are welcome to discuss their own examples.
