AI preliminary evidence assessment
CC 級|AI 整體初步評級
This preliminary assessment is currently available in Traditional Chinese.
Exact question對成人偏頭痛患者,口服單方核黃素(維生素 B2)作為預防治療,相較於安慰劑或相同共照,是否減少偏頭痛發作頻率或偏頭痛天數,並有哪些不良反應?
已驗證評讀顯示納入研究整體支持介入效果。主要限制包括:直接證據僅來自一項55人、治療三個月的隨機安慰劑對照試驗,精確度與外部適用性有限;所有保留來源均僅依摘要評讀,尚未完成全文核查;無法評估摘要未報告的分配隱蔽、盲法細節、失訪、停藥情形、資助、利益衝突或長期傷害。
Why this assessment was given
- 意向治療分析顯示,核黃素相較安慰劑可降低偏頭痛發作頻率與頭痛天數;以頭痛天數至少改善50%定義的反應者比例為59%對15%,摘要報告治療效益所需人數為2.3。摘要未提供各組發作次數或頭痛天數的絕對變化值。
Limitations affecting this assessment
- 直接證據僅來自一個獨立成人隨機安慰劑對照試驗,共 55 人,精確度與可重現性有限。
- 所有選定來源均僅有摘要;無法核實隨機化、分配隱蔽、盲法、基線平衡、完整數值結果及退出或停藥細節。
- 安全性事件很少且追蹤僅 3 個月,無法排除罕見、延遲或長期危害。
- 25 筆僅有書目資料而無摘要的紀錄仍未解決,不能視為排除、陰性證據或額外支持。
- 三篇系統性回顧僅可提供一致性背景,納入族群、配方及設計可能混合;未將其當作獨立受試者或直接療效證據。
- 未提供試驗資助與利益衝突資訊,不推定其存在或不存在。
- 證據只直接適用於每日 400 mg、3 個月的療程,不能外推至其他劑量、療程、複方產品或長期使用。
