Primary research
Case reports and case studies. A case report describes the medical history of a single patient. Case reports are often run together to form a case series, in which the medical histories of more than one patient with a particular condition are described to illustrate an aspect of the condition. There is no control group with which to compare ...
What Is a Case-Control Study?
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. Case-control studies can be used for both exploratory and ...
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 ...
A Practical Overview of Case-Control Studies in Clinical Practice
Case-control studies are one of the major observational study designs for performing clinical research. 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 studies are particularly appropriate for studying disease outbreaks, rare ...
Primary Research
Primary research is any research that you conduct yourself. It can be as simple as a 2-question survey, or as in-depth as a years-long longitudinal study. The only key is that data must be collected firsthand by you. Primary research is often used to supplement or strengthen existing secondary research.
Research Design: Case-Control Studies
Abstract. 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. After cases and controls are identified, researchers "look back" to determine what past events (exposures ...
An Introduction to the Fundamentals of Cohort and Case-Control Studies
In a case-control study, a number of cases and noncases (controls) are identified, and the occurrence of one or more prior exposures is compared between groups to evaluate drug-outcome associations (Figure 1). A case-control study runs in reverse relative to a cohort study. 21 As such, study inception occurs when a patient experiences an ...
Case Control
Case control studies are observational because no intervention is attempted and no attempt is made to alter the course of the disease. The goal is to retrospectively determine the exposure to the risk factor of interest from each of the two groups of individuals: cases and controls. These studies are designed to estimate odds.
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 ...
Case-control study
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. Case-control studies are often used to identify factors that may contribute to a medical condition by comparing subjects who ...
Case-Control Studies
In the module entitled Overview of Analytic Studies it was noted that Rothman describes the case-control strategy as follows: "Case-control studies are best understood by considering as the starting point a source population, which represents a hypothetical study population in which a cohort study might have been conducted.The source population is the population that gives rise to the cases ...
Case-control study: Design, measures, classic example
Case-control studies provide important contributions to medical research as they are efficient and have a comparison group to perform comparative statistical analysis against. The primary outcome of a case-control study is an odds ratio, a statistical measure of the association between a given exposure and an outcome of interest.

Case Control Study: Definition & Examples
Examples. 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: Investigating the impact of exposure to daylight on the health of office workers (Boubekri et al., 2014).
Understanding Research Designs and External Scientific Evidence
Case-control - This retrospective, observational study identifies an outcome of interest and compares a sample of people with that outcome (case) and a sample of people without that outcome (control). This design enables researchers to determine possible differences of previous exposures, experiences, and risk factors—any of which could ...
Observational Studies: Cohort and Case-Control Studies
Cohort studies and case-control studies are two primary types of observational studies that aid in evaluating associations between diseases and exposures. In this review article, we describe these study designs, methodological issues, and provide examples from the plastic surgery literature. Keywords: observational studies, case-control study ...
Guides: Peer-Review and Primary Research: What is a Primary Study
A primary research or study is an empirical research that is published in peer-reviewed journals. Some ways of recognizing whether an article is a primary research article when searching a database: 1. The abstract includes a research question or a hypothesis, methods and results. 2. Studies can have tables and charts representing data findings. 3.
Primary vs. Secondary Sources
Primary Sources. A primary source in science is a document or record that reports on a study, experiment, trial or research project. Primary sources are usually written by the person(s) who did the research, conducted the study, or ran the experiment, and include hypothesis, methodology, and results. Primary Sources include: Pilot/prospective ...

Study Design 101: Case Control Study
Case control studies are observational because no intervention is attempted and no attempt is made to alter the course of the disease. The goal is to retrospectively determine the exposure to the risk factor of interest from each of the two groups of individuals: cases and controls. These studies are designed to estimate odds.
Descriptive Research and Case Studies
Another common problem in case study research is that of reconciling conflicting interpretations of the same case history. Despite these limitations, there are advantages to using case studies. One major advantage of the case study in psychology is the potential for the development of novel hypotheses of the cause of abnormal behavior for later ...
Analysis of matched case-control studies
Analysis of matched case-control studies. There are two common misconceptions about case-control studies: that matching in itself eliminates (controls) confounding by the matching factors, and that if matching has been performed, then a "matched analysis" is required. However, matching in a case-control study does not control for ...
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).
Chapter 6: Systematic Review Overview
Protocols should document the predetermined PICO and study inclusion/exclusion criteria without the influence of the outcomes available in published primary studies 6. The Preferred Reporting Items for Systematic review and Meta-Analysis Protocols (PRISMA-P) framework can be used to guide the development of a systematic review 7 .
