Through regular practice generic 25 mg cozaar fast delivery blood glucose numbers chart, you will learn to write better questions and in turn buy cozaar 25mg with mastercard diabete mellitus mayo clinic, ﬁnd better answers. Sir William Osler (1849–1919) Learning objectives In this chapter you will learn: r the scope and function of the articles you will ﬁnd in the medical literature r the function of the main parts of a research article The medical literature is the source of most of our current information on the best medical practices. This literature consists of many types of articles, the most important of which for our purposes are research studies. In order to evaluate the results of a research study, you must understand what clinical research articles are designed to do and what they are capable of accomplishing. To be an intelli- gent reader of the medical literature, you then must understand which types of articles will provide the information you are seeking. In your medical career, you will read and perhaps also write, many research papers. All medical specialties have at least one primary peer-reviewed journal and most have several. One important observation you will make is that not all journals are created equal. For example, peer-reviewed journals are “better” than non–peer-reviewed journals since their articles are more carefully screened and contain fewer “prob- lems. As the consumer of this literature, you are responsible for determining how to use the results of clinical research. You will also have to translate the results of these research studies to your patients. Many patients these days will read about medical studies in the lay press or hear about them on television, and may even base their decisions about health care upon what the magazine writers or journalists say. Your job as a physician is to help your patient make a more informed medical decision rather than just taking the media’s word for it. In order to do this, you will need to have a healthy skep- ticism of the content of the medical literature as well as a working knowledge of critical appraisal. Other physicians, journal reviewers, and even editors may not be as well trained as you. Non–peer-reviewed and minor journals may still have articles and studies that give good information. All studies have some degree of useful information, and the aforementioned articles are useful for reviewing and relearning background information. A partial list of common and important medical journals is included in the Bibliography. Usually, when asked about articles in the medical literature, one thinks of clini- cal research studies. These include such epidemiological studies as case–control, cohort or cross-sectional studies, and randomized clinical trials. These are not the only types of articles that are important for the reader of the medical liter- ature. There are several other broad types of articles with which you should be familiar, and each has its own strengths and weaknesses. We will discuss studies other than clinical research in this chapter, and will address the common types of clinical research studies in Chapter 6. Basic science research Animal or basic science research studies are usually considered pure research.
