Creatine for Sarcopenia

AI preliminary evidence assessment

U

U 級|AI 整體初步評級

This preliminary assessment is currently available in Traditional Chinese.

Exact question對已診斷或依明確標準界定肌少症的成人,口服單方肌酸,相較於安慰劑或一般照護,是否改善肌力、身體功能、失能或生活品質,並有哪些不良反應?若兩組均接受相同阻力訓練,評估的是肌酸的加成效果;瘦體重僅作輔助結果。

已驗證評讀顯示證據不足以支持本題;目前沒有足以判定療效的直接證據。主要限制包括:沒有符合精確PICO且可萃取病人重要療效結果的直接報告;零篇直接合格報告不代表沒有人體研究,也不能據此推論肌酸無效。

Why this assessment was given

  • 一般高齡全體樣本中,肌酸組的瘦體重增加較多,但兩組10RM臥推與腿推變化無顯著差異。
Limitations affecting this assessment
  • 261筆PubMed候選紀錄完成篩選後,沒有直接符合目標族群與可歸因介入條件的療效報告,故無直接臨床結局證據。
  • PMID 27239423納入的是60至80歲、一般健康且非運動成人;基線僅少數人符合肌少症分期,未提供其可分離的肌力、功能或安全性結果,因此只能作間接背景。
  • PMID 27239423僅有27名完成者、追蹤12週;肌酸加相同阻力訓練雖增加較多瘦體重,但10RM臥推與腿推的組間變化無顯著差異,且未報告失能或生活品質。
  • PMID 27239423報告無肌酸所致的自述副作用,但研究規模小、期間短,無法排除較少見或長期不良反應;兩組各有退出,原因均記為個人因素。
  • PMID 37124482只是brief review的勘誤;PMID 39691097是具肌酸產業利益衝突揭露的意見文章,兩者均未增加新的試驗參與者或直接證據。
  • 瘦體重屬輔助結果,不能替代肌力、身體功能、失能或生活品質等病人重要結局。
  • 此背景讀者事實的必要欄位缺少足夠來源支持,因此未列為讀者研究結果,也未納入評級;同來源其他可驗證資訊仍分開保留。

Reading and assessment notes

Grade U means the verified evidence is insufficient to support a clinical effect for this defined question; it does not establish no effect. Read the method and common limitations.

Absence of reported harms does not establish safety. This summary does not provide individual treatment or dosing advice.
