In their current report for Annals, Sumida and colleagues (1) present important work to understand the relationship between urine protein and albumin. Albuminuria, a marker of kidney disease, is associated with future risk for death, kidney failure, and cardiovascular events (2, 3). The strength of evidence has led to the urine albumin–creatinine ratio (ACR), used to diagnose and stage kidney disease and to predict kidney failure risk (4, 5). The kidney failure risk equation (KFRE) is a validated tool that incorporates ACR, sex, age, and estimated glomerular filtration rate to predict kidney failure (6). Yet, how can ...References1.

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.
