Stádiumfügg

Stádiumfügg is a Hungarian term used in medicine and related sciences to describe a property, relationship, or effect that varies according to the stage of a disease or condition. The noun captures the idea of stage-dependence: the same factor may have different clinical significance in different stages of progression. In practice, stádiumfügg is often used when reporting prognostic factors or diagnostic performance that changes as the disease advances. For example, a biomarker or imaging finding may be strongly associated with outcome in early-stage disease but have diminished or altered relevance in advanced stages. Conversely, some variables may only become informative at later stages.

Linguistically, stádiumfügg derives from stádium (stage) and függő (dependent). In English-language literature, the concept is typically described as stage-dependent or stage-specific; in statistical terms, it relates to interaction effects or effect modification by disease stage.

In research and clinical practice, identifying stádiumfügg is important for risk stratification, treatment planning, and prognostic modeling. It often requires stratified analyses or models that include interaction terms between stage and the factor of interest. Accurate recognition of stage dependence helps avoid misleading conclusions when applying findings across different patient groups or disease stages.
