Evidencebased Medicine OVID Search History 通過圖示說明截詞符及高級檢索方式所檢索的相關字段 Evidencebased Medicine 檢索時應注意的一些問題 根據所選數據庫的不同，檢索界面也略有差異 應根據各相關數據庫的功能選擇有關的檢索模塊 如以下數據庫可選“ Search Tools‖： CCTR MEDLINE HTA EED等 應注意“ Search Fields‖ 中有的字段只對部分數據庫起作用。 如： Publication Type針對的是 CCTR和 MEDLINE數據庫 Evidencebased Medicine 中、英文數據庫介紹 (2) 檢索 Cochrane Library Cochrane圖書館 (CLIB)是一個的收集高質量衛(wèi)生保健決策證據的檢索系統， CLIB協作網系統評價是基于臨床治療決策的高水平證據，除此之外， CLIB圖書館還收集有來自衛(wèi)生技術評價、經濟評價等系統評價的摘要信息和單個臨床試驗相關信息等資源，系統提供的檢索界面可對多個數據庫同時進行檢索。 Evidencebased Medicine Cochrane Library的出版方式 1996年由 Update Software公司出版發(fā)行了第 1期 CLIB（光盤版）。此后，CLIB又有了網絡版，內容仍為每季更新，更新后的光盤覆蓋以前的內容。從 2022年起，CLIB改由 Willey公司（ John Wiley amp。 Sons Ltd.）出版發(fā)行，仍為光盤版和網絡版。 Evidencebased Medicine Cochrane Library網絡版 : Evidencebased Medicine Cochrane Library的圖標 Evidencebased Medicine Cochrane Library的高級檢索 Evidencebased Medicine Cochrane Library的瀏覽和檢索 Evidencebased Medicine 從 Cochrane Library中檢索 肺癌 1 MeSH descriptor Lung Neoplasms explode all trees 2 lung near cancer* 3 lung near neoplasm* 4 lung near carcinoma* 5 lung near tumour* 6 lung near tumor* 7 1 or 2 or 3 or 4 or 5 or 6 Evidencebased Medicine Box : Demonstration search strategy for CENTRAL, for the topic ‘Tamoxifen for breast cancer’ — 《 Cochrane系統評價手冊 》 1 MeSH descriptor Breast Neoplasms explode all trees 2 breast near cancer* 3 breast near neoplasm* 4 breast near carcinoma* 5 breast near tumour* 6 breast near tumor* 7 1 or 2 or 3 or 4 or 5 or 6 8 MeSH descriptor Tamoxifen explode all trees 9 tamoxifen 10 8 or 9 11 7 and 10 The 39。near39。 operator defaults to within six words。 ‘*’ indicates truncation. Evidencebased Medicine 檢索 Cochrane圖書館碰到的一個有趣的檢索結果 3的命中數多于 1 OR 2 為什么？ Evidencebased Medicine Cochrane協作網信息檢索專業(yè)組“ Email討論”專家的回復： Once you use a truncation sign you turn off the automatic function. 1 (breast near tumour*) 254 2 (breast near tumor*) 428 3 breast near tumour 640 4 (1 OR 2) 670 5 (3 AND NOT 4) 0 6 (4 AND NOT 3) 30 If you do 39。1 or 239。 you will get 670 hits – 30 more than you would using the automatic function (you would need to check these , but probably shows that it is worth using truncation). Evidencebased Medicine Cochrnae Library的部分檢索規(guī)則 對多個詞同時檢索，詞與詞間默認有“ AND‖邏輯運算符；可用 ,代替 OR邏輯運算符，例如：gene, therapy可替代 gene OR therapy 對詞組（短語）進行精確檢索，應加上雙引號，例如： “ clodronate therapy‖ 緊鄰的兩詞之間可使用“ next‖進行鄰近檢索； 使用“ near‖相鄰位置算符默認狀態(tài)為將兩詞限定在 6個詞以內， near/后的數字表示兩詞之間允許有的詞數。 Evidencebased Medicine 檢索時需要注意的一些問題 在檢索中尤其需要將主題詞檢索和關鍵詞檢索結合起來制定檢索策略； 對 標題 、 作者 字段的限定檢索可針對所有的數據庫；對 摘要 字段的限定檢索可針對 DARE和 Clinical Trails (CENTRAL) ； 對 publication type（出版物類型）字段的限定檢索僅針對 Clinical Trails (CENTRAL) 。 Evidencebased Medicine 中、英文數據庫介紹 (3) 檢索中國生物醫(yī)學文獻數據庫 CBM Evidencebased Medicine 中國生物醫(yī)學文獻數據庫 （新的檢索平臺） Evidencebased Medicine 中國生物醫(yī)學文獻數據庫 （新的檢索平臺） Evidencebased Medicine 中國生物醫(yī)學文獻數據庫 （新的檢索平臺） Evidencebased Medicine 中、英文數據庫介紹 (4) 中國生物醫(yī)學期刊引文數據庫 Evidencebased Medicine CMCI基本檢索 Evidencebased Medicine CMCI引文檢索 Evidencebased Medicine 中、英文數據庫簡介 (4) PubMed Evidencebased Medicine PubMed Clinical Queries Evidencebased Medicine PubMed MeSH Evidencebased Medicine PubMed Limits Evidencebased Medicine PubMed Advanced Search Evidencebased Medicine Box : Cochrane Highly Sensitive Search Strategy for identifying randomized trials in MEDLINE: sensitivitymaximizing version (2022 revision)。 PubMed format 1 randomized controlled trial [pt] 2 controlled clinical trial [pt] 3 randomized [tiab] 4 placebo [tiab] 5 drug therapy [sh] 6 randomly [tiab] 7 trial [tiab] 8 groups [tiab] 9 1 or 2 or 3 or 4 or 5 or 6 or 7 or 8 10 animals [mh] not humans [mh] 11 9 not 10 注 : Publication Type [PT] Title/Abstract [TIAB] MeSH Subheadings [SH] MeSH Terms [MH] Evidencebased Medicine Box : Cochrane Hig
