A case series (also known as a clinical series) is a medical research study that tracks patients with a known exposure or examines their medical records for exposure and outcome. A case series can be retrospective or prospective and usually involves a smaller number of patients than more powerful case-control studies or randomized controlled trials.
A case series is a type of observational study. Case series may be consecutive or non-consecutive, depending on whether all cases presenting to the reporting authors over a period of time were included, or only a selection.
