Some Common Types of Scientific / Health Sciences Articles

Clinical Trial: From the National Institutes of Health, "Clinical trials look at new ways to prevent, detect, or treat disease. Treatments might be new drugs or new combinations of drugs, new surgical procedures or devices, or new ways to use existing treatments. The goal of clinical trials is to determine if a new test or treatment works and is safe. Clinical trials can also look at other aspects of care, such as improving the quality of life for people with chronic illnesses."

Meta-Analysis: A quantitative analysis that reviews data from previous research done on a particular topic to better draw conclusions about that research and topic. See Meta-analysis in Medical Research for more information.

Randomized Controlled Trial: A clinical trial or study where participants are randomly assigned to different groups. See Randomized Controlled Trial (RCT) from the National Library of Medicine for more information.

Systematic Review: A literature review that not only compiles, but also analyzes all the pertinent literature on a specific topic. The review attempts to answer a research question and it can be a very valuable source of resources for your work. See Cochrane's What is a Systematic Review for more information.
