Advantages and Disadvantages of Case-Control Studies
Advantages and Disadvantages of Case-Control Studies. They are efficient for rare diseases or diseases with a long latency period between exposure and disease manifestation. They are less costly and less time-consuming; they are advantageous when exposure data is expensive or hard to obtain. They are advantageous when studying dynamic ...
A Practical Overview of Case-Control Studies in Clinical Practice
Study design considerations are reviewed, including sample size, power, and measures associated with risk factors for clinical outcomes. Finally, we discuss the advantages and disadvantages of case-control studies and provide a checklist for authors and a framework of considerations to guide reviewers' comments.
Case Control Studies
A case-control study is a type of observational study commonly used to look at factors associated with diseases or outcomes.[1] The case-control study starts with a group of cases, which are the individuals who have the outcome of interest. The researcher then tries to construct a second group of individuals called the controls, who are similar to the case individuals but do not have the ...
What Is a Case-Control Study?
Case-control studies are a solid research method choice, but they come with distinct advantages and disadvantages. Advantages of case-control studies. Case-control studies are a great choice if you have any ethical considerations about your participants that could preclude you from using a traditional experimental design.
Case Control Studies
Because of these advantages, case-control studies are commonly used as one of the first studies to build evidence of an association between exposure and an event or disease. In a case-control study, the investigator can include unequal numbers of cases with controls such as 2:1 or 4:1 to increase the power of the study. Disadvantages and ...
Epidemiology in Practice: Case-Control Studies
Introduction. 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).
A Practical Overview of Case-Control Studies in Clinical Practice
The advantages of these study designs over other study designs are that they are relatively quick to perform, economical, and easy to design and implement. Case-control ... we discuss the advantages and disadvantages of case-control studies and provide a checklist for authors and a framework of considerations to guide reviewers' com-ments ...
Case Control
Case control studies are also known as "retrospective studies" and "case-referent studies." Advantages Good for studying rare conditions or diseases Less time needed to conduct the study because the condition or disease has already occurred Lets you simultaneously look at multiple risk factors Useful as initial studies to establish an association
Case-control and Cohort studies: A brief overview
Introduction. Case-control and cohort studies are observational studies that lie near the middle of the hierarchy of evidence. These types of studies, along with randomised controlled trials, constitute analytical studies, whereas case reports and case series define descriptive studies (1). Although these studies are not ranked as highly as ...

Introduction to Epidemiological Studies
Case-control studies identify the study groups based on the outcome, and the researchers retrospectively collect the exposure of interest. The present chapter discusses the basic concepts, the advantages, and disadvantages of epidemiological study designs and their systematic biases, including selection bias, information bias, and confounding.

Study design considerations are reviewed, including sample size, power, and measures associated with risk factors for clinical outcomes. Finally, we discuss the advantages and disadvantages of case-control studies and provide a checklist for authors and a framework of considerations to guide reviewers' comments.
A case-control study (also known as a 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. It is designed to help determine if an exposure is associated with an outcome (i.e., disease or condition of interest).
Case-control studies: Part 2
Case-control studies: Part 2. In the previous article, I defined the case-control study and discussed issues regarding the selection of controls. In this second article devoted to case-control studies, I will discuss bias and the advantages and disadvantage of this clinical study design.
Case-control studies: advantages and disadvantages
Case-control studies: advantages and disadvantages. Researchers investigated the risk factors associated with the development of pulmonary tuberculosis in Russia. A case-control study was performed in the city of Samara, 700 miles south east of Moscow. Cases were 334 consecutive adults diagnosed as having culture confirmed pulmonary ...
When is it Desirable to Conduct a Case-Control Study?
Case-control studies are advantageous under the following circumstances: When exposure data are expensive or difficult to obtain, e.g., assessing pesticide levels in blood or other medical tests. When the disease has a long induction and/or latent period, e.g., cancer, dementia. With a case-control study one does not have to wait for disease to ...
Nested case-control studies: advantages and disadvantages
a) The nested case-control study is a retrospective design. b) The study design minimised selection bias compared with a case-control study. c) Recall bias was minimised compared with a case-control study. d) Causality could be inferred from the association between prescription of antipsychotic drugs and venous thromboembolism.

Vegetables and Fruits
Eat plenty every day. A diet rich in vegetables and fruits can lower blood pressure, reduce the risk of heart disease and stroke, prevent some types of cancer, lower risk of eye and digestive problems, and have a positive effect upon blood sugar, which can help keep appetite in check. Eating non-starchy vegetables and fruits like apples, pears ...
Bias in full cohort and nested case-control studies?
Generally, the only disadvantages to nested case-control studies are the reduced precision and power due to sampling of controls, and the possibility of flaws in the sampling design or its implementation. Therefore, any problem with nested case-control studies must also be a problem for full cohort analysis. Demonstration of this (or an ...
