Disfunción tiroidea como predictor de sarcopenia. Una revisión sistemática
Bibliographic record
Abstract
Objetivo: Evaluar el papel de la disfunción tiroidea como predictor de sarcopenia en adultos mayores. Material y métodos: Revisión sistemática basada en PRISMA 2020. Se buscaron estudios observacionales en PubMed y EMBASE. La selección y extracción de datos fueron realizadas por dos revisores de forma independiente. La calidad metodológica se evaluó con la escala Newcastle-Ottawa. Resultados: Se incluyeron 27 estudios de adultos ≥65 años. Niveles bajos de FT3 se asociaron con mayor sarcopenia y fragilidad, mientras que FT4 alto aumentó el riesgo de sarcopenia. La relación TSH-sarcopenia fue variable, y el hipertiroidismo subclínico se vinculó con mayor fragilidad. Conclusiones: La función tiroidea influye en la sarcopenia en adultos mayores. Niveles bajos de T3 aumentan el riesgo de fragilidad, mientras que FT4 elevado contribuye a la pérdida muscular. La relación con TSH es variable. Factores como edad y comorbilidades deben considerarse, destacando la necesidad de criterios diagnósticos estandarizados y el monitoreo de T3 para prevenir la pérdida funcional.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
