Diabetes Care, 1989
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 ...

JAMA: The Journal of the American Medical Association, 1982
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-

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 ...

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 ...

Neurology, 2005
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.

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 and bayesian inference
Statistics in Medicine, 1986AbstractWe outline the methods of Bayesian inference for applications to case‐control studies. These methods appear as the natural way of making inferences, since much of the controversy that surrounds a specific case‐control study is subjective. We derive conjugate prior distributions of exposure, posterior distributions of the ratio of the odds of ...

Case-Control Studies of Screening
International Journal of Epidemiology, 1991The application of case-control studies to the evaluation of screening data presents a number of potential problems. In particular, the results are liable to be affected by selection bias. Published case-control studies of breast cancer screening are reviewed in the light of the results of a recent UK study of somewhat different design which attempts ...
