Pooled analyses, duplicates, and studies with nonextractable data were excluded. Response, remission, and baseline-endpoint or mean reductions scores of the Hamilton Anxiety Rating Scale (HARS) were extracted. The Cochrane Collaboration's computer program, Review Manager, version 5, with a random effects model, was used to pool results.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>A total of 50 articles were cited as evidence for managing GAD by the CPA. There was sufficient evidence of remission with first- or third-line agents to pool reported rates, and with agents from all 3 treatment lines to pool response rates and reduction in HARS scores. The mean range of effect size varied considerably from study to study within each treatment line. Comparison of pooled remission rates between first- and second-line agents was not possible. While the range of values by drug and drug class overlapped, the summary results for the probability of response and reduction in HARS scores was greater for first-line, compared with second-line, treatments. Drug components for third-line treatments were heterogeneous and produced mixed results.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Despite the abundance of evidence in its totality presented in the CPA guidelines, there is inadequate evidence to formulate recommendations based on the pooled results from this study alone. However, such analysis provides an additional resource for clinicians to make more effective treatment decisions for individual patients with GAD.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/070674371205700805","type":"journal-article","created":{"date-parts":[[2017,7,20]],"date-time":"2017-07-20T09:56:06Z","timestamp":1500544566000},"page":"470-478","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":25,"title":["Evidence-Based Review of Clinical Outcomes of Guideline-Recommended Pharmacotherapies for Generalized Anxiety Disorder"],"prefix":"10.1177","volume":"57","author":[{"given":"Basil G","family":"Bereza","sequence":"first","affiliation":[{"name":"Student, Leslie Dan Faculty of Pharmacy, University of Toronto, Toronto, Ontario"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M\u00e1rcio","family":"Machado","sequence":"additional","affiliation":[{"name":"Research Associate, Toronto Health Technology Assessment Collaborative, University of Toronto, Toronto, Ontario; Assistant Professor, Leslie Dan Faculty of Pharmacy, University of Toronto, Toronto, Ontario"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Arun V","family":"Ravindran","sequence":"additional","affiliation":[{"name":"Professor, Department of Psychiatry, University of Toronto, Toronto, Ontario; Clinical Director, Centre for Addiction and Mental Health, Toronto, Ontario"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Thomas R","family":"Einarson","sequence":"additional","affiliation":[{"name":"Associate Professor, Leslie Dan Faculty of Pharmacy, University of Toronto, Toronto, Ontario"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2012,8,1]]},"reference":[{"key":"bibr1-070674371205700805","first-page":"7S","volume":"51","year":"2006","journal-title":"Can J Psychiatry"},{"key":"bibr2-070674371205700805","doi-asserted-by":"publisher","DOI":"10.1046\/j.1532-5415.2002.50003.x"},{"key":"bibr3-070674371205700805","doi-asserted-by":"publisher","DOI":"10.1097\/01.jcp.0000155821.74832.f9"},{"key":"bibr4-070674371205700805","doi-asserted-by":"publisher","DOI":"10.1002\/14651858.CD003592"},{"key":"bibr5-070674371205700805","doi-asserted-by":"publisher","DOI":"10.1016\/j.jad.2004.11.011"},{"key":"bibr6-070674371205700805","volume-title":"Poster presented at the 22nd National Conference of the Anxiety Disorders Association of America","author":"Davidson JRT","year":"2002"},{"key":"bibr7-070674371205700805","doi-asserted-by":"publisher","DOI":"10.1016\/S0924-977X(99)80423-4"},{"key":"bibr8-070674371205700805","unstructured":"Hackett D, Salinas E, Rudolph RL, for the Venlafaxine XR 378 Study Group.
