2023年2月4日 · Case-control studies are a type of observational study often used in fields like medical research, environmental health, or epidemiology. While most observational studies are qualitative in nature, case-control studies can also be quantitative , and they often are in healthcare settings.

A case–control study (also known as case–referent study) is a type of observational study in which two existing groups differing in outcome are identified and compared on the basis of some supposed causal attribute.

2023年7月31日 · A case-control study is an observational study where researchers analyzed two groups of people (cases and controls) to look at factors associated with particular diseases or outcomes. Below are some examples of case-control studies:

Case-control studies are one of the most frequently used study designs for these purposes. This paper explains basic features of case control studies, rationality behind applying case control design with appropriate examples and limitations of this design.

Case-control studies are observational studies in which cases are subjects who have a characteristic of interest, such as a clinical diagnosis, and controls are (usually) matched subjects who do not have that characteristic.

Case-control studies are one of the two main types of observational study designs in epidemiology. This design is desirable when exposure data are difficult to obtain, the disease is rare or has a long induction period, or when the underlying population is dynamic.

A case-control study is designed to help determine if an exposure is associated with an outcome (i.e., disease or condition of interest). In theory, the case-control study can be described simply. First, identify the cases (a group known to have the outcome) and the controls (a group known to be free of the outcome).

In a case-control study the researcher identifies a case group and a control group, with and without the outcome of interest. Such a study design is called observational because the researcher does not control the assignment of a subject to one of the groups, unlike in a planned experimental study. In a classic case-control study, the outcome of
