DEF

A statistical method that allows for ending an experiment as soon as a response with the desired precision is obtained, with each outcome being examined as soon as it occurs and being added to all the previous outcomes.

OBS

The main advantage of a sequential trial is as follows: 1) it is shorter than a fixed-length trial when there is a large difference in the effectiveness of the interventions being compared; or 2) a trial can be terminated quickly when there is a health risk. Since, with this approach, the assignment of the treatments generally must be known before the study, special methods for the analysis and dissemination of interim results are required.

OBS

sequential trial: term and definition standardized by the Health Technology Assessment (HTA) Glossary English Editorial Board and the Translation Bureau.

DEF

Méthode statistique qui permet de mettre fin à une expérience dès qu’on obtient une réponse ayant la précision souhaitée, chaque résultat étant examiné dès qu’il est obtenu et ajouté à tous les résultats antérieurs.

OBS

Un essai avec analyse séquentielle a pour principal avantage : 1) d’être plus court qu’un essai de durée fixe lorsqu’il y a une grande différence d’efficacité dans les interventions comparées; ou 2) de permettre d’interrompre rapidement un essai lorsqu’il y a risque pour la santé. Comme cette approche exige généralement que l’allocation des traitements soit connue avant la fin de l’étude, des méthodes spéciales d’analyse et de diffusion des résultats intermédiaires sont requises.
