Meta-analysis A process often applied to data from multiple systematic reviews. This process often results in a statistical analysis of sources.
Systematic Review A summary of primary research studies used to answer a specific question. A Systematic Review is usually the result of a comprehensive literature review that has been conducted using predefined criteria.
Randomized Controlled Clinical Trials (RCTs) Trials that involve at least one experimental treatment or intervention and one control treatment or intervention (either a placebo treatement or no treatment) conducted over a period of time.
Double Blind Randomized Control Trials Trials that utilize the framework of the Randomized Control Trial combined with the additional qualification that neither the patient nor the investigator knows whether or not the patient is receiving the experimental treatment or control treatment.
Cohort Studies Studies that make observations about the connection between a particular exposure or risk factor and the subsequent development of a disease or condition. In Cohort Studies, subjects initially do not have the condition being studied. They are followed over time to see if or what frequency they develop the disease/condition as compared with a control group not exposed to the risk factor under investigation.
Case Control Studies Comparison of a group of patients, one of which already has a condition or disease and one without the disease or condition.
Case Series or Care Reports Reports on the treatment of one or more individual patients.
