Notes:
PM limited: PM's Clinical Query 'Therapy/Narrow' is too narrow and CQ 'Therapy/Broad' is too broad. PubMed's own 'filter' (randomized controlled trial[pt]) looses non-indexed ('PreMedline') items. Orig. drafted 21 Nov 2013. OT-tag added to find author keywords, 16 Jan 2014. PM extensive: from: Cochrane Handbook, Version 5.0.1, [updated September 2008], eds: Higgins & Green, box 6.4.a: Cochrane Highly Sensitive Search Strategy for identifying randomized trials in MEDLINE: sensitivity-maximizing version (2008 revision) [http://www.mrc-bsu.cam.ac.uk/cochrane/handbook/chapter_6/box_6_4_a_cochrane_hsss_2008_sensmax_pubmed.htm]. Notation as a search string by Ket, Jan 2009. This filter differs from the 'Clinical trial'-filter as the above filter will only find randomized controlled trials and not the more broad search for 'clinical trials' in the 'Clinical Trials'-filter. Embase.com extensive: From: Cochrane Handbook, Version 5.0.1, [updated September 2008], eds: Higgins & Green, chapter 6.3.2.2, What is in The Cochrane Central Register of Controlled Trials (CENTRAL) from EMBASE? [http://www.cochrane-handbook.org], notation as a search string by Ket (Jan 2009). This search string is based on research by the UK Cochrane Centre "for reports of trials not indexed as trials in MEDLINE (Lefebvre 2008)." From: Cochrane Handbook, chapter 6.3.2.2. Revision by De Vries, Sep 2013). PsycInfo extensive, CINAHL extensive and Web of Science extensive originally drafted by Cochrane Collaboration, received by e-mail from Sarah Dawson, 21 Jun 2016 and adapted by Ket, 5 Jul 2016. CINAHL corrected by Thomas Pelgrim, 15 Jan 2018. For CINAHL the filter includes the 'Treatment as usual'-filter. For PsycInfo the OVID/PI-filter was translated to EBSCO/PsycInfo by Ket, 5 Jul 2016.
