The implantable cardioverter defibrillator (ICD) is an effective but expensive therapy for primary and secondary prevention of this disorder (1, 2). Because health care resources are limited, when therapies are both effective and expensive, one must consider whether the benefits are worth the expense. A cost-effectiveness analysis answers that question by calculating the ratio of incremental cost to incremental effectiveness. Comparisons to other therapies are then possible. The lower the incremental cost-effectiveness ratio, the better the use of resources and the more ...References1. Ezekowitz JA, Armstrong PW, McAlister FA.

Prédiction machine sur la base complète
Imitation des enseignantsNi prévalence calibrée, ni vérité terrain. Validation humaine à venir. Le volet Gemma est une étiquette directe du modèle pour chaque travail de la base, lue sur la notice réduite au titre. Le volet Codex est un classifieur appris des 10 348 étiquettes directes de Codex et calibré sur les taux pondérés de l'échantillon; les champs sans appui suffisant ne portent aucun appel Codex. Le mode candidate est l'union des deux volets; le consensus est leur intersection. Ces sorties portent le statut machine_predicted_unvalidated et ne sont pas des étiquettes humaines.
