On the whole cheap 100mg avana with visa, absence of evidence of an effect is not the same thing as evidence of absence of an effect discount avana 200mg with mastercard. Conclusion The study results should be accurately reﬂected in the conclusion section generic 50 mg avana overnight delivery, a one-paragraph summary of the ﬁnal outcome avana 100mg visa. The reader should be aware that pitfalls in the inter- pretations of study conclusions include the use of biased language and incorrect interpretation of results not supported by the data discount avana 50mg. Studies sponsored by drug companies or written by authors with other conﬂicts of interest may be more prone to these biases and should be regarded with caution. All sources of con- ﬂict of interest should be listed either at the start or at the end of the article. Bibliography The references/bibliography section demonstrates how much work from other writers the author has acknowledged. This includes a comprehensive reference list including all important studies of the same or similar problem. You will be better at interpreting the completeness of the bibliography when you have immersed yourself in a specialty area for some time and are able to evaluate this author’s use of the literature. Be wary if there are multiple citations of works by just one or two authors, especially if by the author(s) of the current study. The New England Journal of Medicine is a great place for medical students to start. It publishes important and high quality studies and includes a lot of correlation with basic sciences. There are also excellent case discussions, review articles, and basic-science articles. Remember, that what you read in the abstract should not be used to apply the results of the study to a clinical scenario. Initially, we will focus on learning how to criti- cally evaluate the most common clinical studies. These skills will help you to grade the quality of the studies using a schema outlined in Appendix 1. Later the book will focus on studies of diagnostic tests, clinical decision making, cost analyses, prognosis, and meta-analyses or systematic reviews. But as for certain truth, no man has known it, for all is but a woven web of guesses. This requires one to develop an effective search strategy for a clinical question. By the end of this chapter you will understand how to write a clinical question and formulate a search of the literature. Once an answerable clinical question is written and the best study design that could answer the ques- tion is decided upon, the next task is to search the literature to ﬁnd the best avail- able evidence. This might appear an easy task, but, unless one is sure of which database to use and has good searching skills, it can be time-consuming, frus- trating, and wholly unproductive. This chapter will go through some common databases and provide the information to make the search for evidence both efﬁ- cient and rewarding. Introduction Finding all relevant studies that have addressed a single question is not an easy task. The exponential growth of medical literature necessitates a systematic 33 34 Essential Evidence-Based Medicine searching approach in order to identify the best evidence available to answer a clinical question. While many people have a favorite database or website, it is important to consult more than one resource to ensure that all relevant informa- tion is retrieved. Developed by the National Library of Medicine at the National Institutes of Health in the United States, it is the world’s largest gen- eral biomedical database and indexes approximately one-third of all biomedi- cal articles. Since it was the ﬁrst medical literature database available for elec- tronic searching, most clinicians are familiar with its use. Due to its size and breadth, it is sometimes a challenge to get exactly what one wants from it. This will be the ﬁrst database discussed, after a discussion of some basic principles of searching. The database selected depends on the content area and the type of question being asked. If search- ing for the answer to a question of therapy or intervention, then the Cochrane Library might be a particularly useful resource. It provides systematic reviews of trials of health-care interventions and a registry of controlled clinical trials.
