Clinical Case Series: Is the most basic type of study design, in which researchers describe the experience of a group of people. Case series describe individuals who develop a particular new disease or condition. This type of study can provide compelling reading because they present a detailed account of the clinical experience of individual study subjects. Dr. Alex Jimenez conducts his own case series studies.

Case-Series is a descriptive study design and its just a series of cases of any particular disease or disease discrepancy that one might observe in a clinical practice. Case series can describe and show the results of functional medicine and working with a health coach. These cases are described to suggest at best a hypothesis. However, there is no comparison group so there cannot be many conclusions about the disease or the disease process. Therefore, in terms of generating evidence regarding various aspects of a disease process this is more of a starting point.
