Carbajal, Huang, and Hu that several trials included in our systematic review had potential methodologic deficiencies. Although we had space to highlight only 1 of these deficiencies in our published manuscript (randomization after implantation of the CRT device in all but 1 trial), we refer interested readers to our full Agency for Healthcare Research and Quality report, available at www.ahrq.gov/clinic/tp/resyntp.htm, for a full description of the methods and the quality assessment tables for all of the studies included in both our efficacy and safety analyses.We refute the allegation of Drs. Calvert, Freemantle, and ...References1. Bristow MR, Saxon LA, Boehmer J, Krueger S, Kass DA, De Marco T, et al.

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.

Scores machine (provisoires)
Les deux têtes enseignantes du modèle étudiant, lues sur ce travail. Un score ordonne la base pour la relecture; il n'affirme jamais une catégorie, et le statut de validation accompagne chaque rangée tel quel.
Scores de référence d'un modèle non mature (critères de maturité non atteints, 7 itérations). Un score ordonne; il n'affirme jamais une catégorie.
score_only:v0-immature-baseline · tel quel depuis la passe de notation : score_only signifie que le nombre peut ordonner les travaux, et qu'aucune étiquette de catégorie n'en découleClassification
machine, non validéePrédiction automatique; un appel candidat d’une seule source (Gemma direct ou Codex distillé), pas un consensus.
