The Lancet Correspondence: FYTF-919 and CHAIN Trial Review

Vocabulary flashcards detailing key study definitions, statistical methodologies, diagnostic thresholds, and participant details from the provided Lancet correspondence text.

FYTF-919

A traditional Chinese medicine (Zhongfeng Xingnao oral prescription) evaluated for acute intracerebral haemorrhage that possesses potential anti-neuroinflammatory and antithrombotic effects.

Moderate to Severe Intracerebral Haemorrhage Inclusion Criteria

Study criteria defined by either a score of $8$ or more on the National Institutes of Health Stroke Scale or a score of $7\text{ to }14$ on the Glasgow Coma Scale.

Perihaematomal Oedema Peak

The period following the onset of intracerebral haemorrhage symptoms when tissue swelling peaks, identified as $7\text{ to }10\text{ days}$.

CHAIN Trial Hospital Participation

A trial recruitment process where $27$ hospitals were approached, but $1$ hospital enrolled zero patients, resulting in $26$ active participating hospitals.

Baseline Covariate Model Adjustment Shift

A statistical occurrence where model estimates differ in direction from descriptive data, particularly when the adjusted effect is close to zero for a mean difference or close to unity for an odds ratio.

Floor Effect (Neurointensive Care)

A trial phenomenon where high, guideline-adherent baseline critical care in a neurointensive care unit improves overall outcomes, masking additional potential benefits of an intervention compared to standard care.
