Editor's note: This is the eighth article in a series on clinical research by nurses. The series is designed to give nurses the knowledge and skills they need to participate in research, step by step. Each column will present the concepts that underpin evidence-based practice—from research design to data interpretation. The articles will be accompanied

European Journal of Epidemiology, 2004
This paper summarizes several studies that can be appended to conventional case-control studies especially in the context of case-control studies that focus on etiologic questions. Appending studies to case-control studies may further add to the understanding of the epidemiology of diseases under investigation.

Case-control studies are largely used to explore differences between groups of individuals. They can identify potential risk factors associated with disease, or they can investigate patient behaviour, such as why some people do not attend for services.

Insulin-dependent diabetes mellitus (IDDM) may be caused by a combination of genetic predisposition and environmental insults. However, there are few solid leads concerning human diabetogenic environmental agents. A case-control study was carried out to investigate the possible relationships between IDDM and various biological, chemical, and ...

The case-control design is very suitable when dealing with rare diseases and when many factors for the disease under study need to be evaluated, as is the case in determining the risk of driving under the influence of drugs. However, the methodology is hard to implement and there are many sources of potential bias that could affect the validity of the ...

OVERADJUSTMENT IN CASE-CONTROL STUDIES
American Journal of Epidemiology, 1980In analyzing data from case-control studies to identify association between an exposure variable and disease status, other variables may be considered as potential confounding variables. Even when a variable has no causal association with disease (we assume that in the underlying population it is not related to disease conditional on the exposure ...

To the Editor.— The article by Hayden et al (1982;247:326-331) on the methodology of the case-control study contains a factual error in describing articles published previously. 1,2 They report that in two studies of reserpine and breast cancer, "patients with thyrotoxicosis, renal disease, or cardiovascular disease were excluded from the control, non-

American Journal of Epidemiology, 1981
A financial review of five case-control studies concerning the relationship of birth control methods to the occurrence of disease was conducted. The review had two major objectives: first, to identify costs associated with the planning, conduct and analysis of case-control studies; second, to assess whether sample size determination based on optimal ...

To examine the influence of various factors on the risk of sudden unexpected death in epilepsy (SUDEP).The authors investigated 154 cases in which a postmortem examination was performed. Each case had four controls with epilepsy from the community, matched for age and geographic location.

The Case-Control Study in Psychiatry
British Journal of Psychiatry, 1990Case-control studies involve ‘cases' being compared to ‘controls' with respect to ‘exposures', possible aetiological (or associated) factors. Associations between a disease and an exposure can be explained by chance, reverse causality, confounding and biases or, lastly, by causality.
