| 설명 | 분석역학에서의 요인-대조연구의 한 기법이다. 사람의 집단에서 질병유행과 가설요인과의 연관성을 고찰하여 인과관계를 밝히는 것을 목적으로 한다. 가설요인을 갖는 집단과 갖지 않는 집단, 혹은 적은 집단과 많은 집단의 2군(코호트)으로 나누어 추적 조사하여 각 집단에서의 질병의 발생빈도를 비교하는 것이다. 일반적으로는 전향적인 연구로 행해지는 경우가 많으나 후향적인 연구로도 행하여진다. |

| cohort study | A study using epidemiological methods, such as a clinical trial, in which a cohort with a particular attribute (e.g., smokers, recipients of a drug) is followed prospectively and compared for some outcome (e.g., disease, cure) with another cohort not possessing the attribute. (05 Mar 2000) |

| cohort | <statistics> A cohort is a group of animals of the same species, identified by a common characteristic, which are studied over a period of time as part of a scientific or medical investigation. (09 Oct 1997) |
|---|---|
| cohort effect | Variation in health status arising from different causal factors to which each birth cohort in a population is exposed as environment and society change. (12 Dec 1998) |
| cohort studies | Studies in which subsets of a defined population are identified. These groups may or may not be exposed to factors hypothesised to influence the probability of the occurrence of a particular disease or other outcome. Cohorts are defined populations which, as a whole, are followed in an attempt to determine distinguishing subgroup characteristics. (12 Dec 1998) |
| analytic study | In epidemiology, a study designed to examine associations, commonly putative or hypothesised causal relationships; usually concerned with identifying or measuring the effects of risk factors or with the health effects of specific exposures. (05 Mar 2000) |
| blinded study | Clinical trials of drugs are often done blinded so that the patient does not know (is blinded as to) whether they are receiving the product being tested or the control/placebo to ensure that the results of a study are not affected by a possible placebo effect (by the power of suggestion). (12 Dec 1998) |
| blind study | A study in which the experimenter is unaware of which group is subject to which procedure. (05 Mar 2000) |
| case-control study | <epidemiology> A study in which the risk factors of people with a disease are compared with those without a disease. It is an epidemiological method that begins by identifying persons with the disease or condition of interest (the cases) and compares their past history of exposure to identified or suspected risk factors with the past history of similar exposures among persons who resemble the cases but do not have the disease or condition of interest (the controls). The relationship of an attribute to the disease can therefore be examined by comparing affected and non-affected individuals with regard to the frequency or levels of the attribute in each group. (05 May 2002) |
| retrospective study | <epidemiology> A study in which people are enrolled and then have their history of risks, infections or disease measured. (05 Dec 1998) |
| rosenzweig picture-frustration study | A projective test depicting cartoon-like characters in frustrating situations. The scoring of the subject's responses indicates the direction of hostility or aggression, that is, whether he blames himself, the other person, or the set of circumstances. (12 Dec 1998) |
| pioped study | <radiology> 251 patients with documented PE on pulmonary angiograms were given V/Q scans: 102 high probability, 105 intermediate probability, 39 low probability, 5 normal or near-normal (12 Dec 1998) |
| multicenter study | A controlled study executed by several cooperating institutions. (12 Dec 1998) |
| multigeneration study | Toxicity test in which at least 3 generations of the test organisms are exposed to the substance being assessed. Exposure is usually continuous. Any medical study which follows a family of people through several generations. (09 Oct 1997) |
| crossover study | <statistics> A study that compares two or more treatments or interventions in which the subjects or patients, upon completion of the course of one treatment, are switched to another. Usually refers to a study in which the subject is switched from the experimental to the control procedure (or vice versa). In the case of two treatments, a and b, half the subjects are randomly allocated to receive these in the order a, b and half to receive them in the order b, a. A criticism of this design is that effects of the first treatment may carry over into the period when the second is given. With this type of study, every patient serves as his or her own control. (21 Jun 2000) |
| cross-sectional study | <epidemiology> A study in which the presence or absence of disease or other health-related variables are determined in each member of the study population or in a representative sample at one particular time. This contrasts with longitudinal studies which are followed over a period of time. Synonym: horizontal study. (18 Jul 2002) |
| preclinical study | A study to test a drug, procedure or other medical treatment in animals. The aim is to collect data in support of safety. Preclinical studies are required before clinical trials can be started. (12 Dec 1998) |
| cohort study |
Observational study of people with known levels of exposures to causal or protective agents, who are followed over a period of time; disease rates are compared between the exposed and the unexposed.

| cohort study |
An epidemiology study that observes a large group of people over a period of time. Within the cohort, morbidity or mortality rates can be calculated for group members with different exposures.

| cohort study |
a study that follows a large group of people over a long period of time, often 10 years or more. In cohort studies, dietary information is gathered before disease occurs, rather than relying on recall after disease develops.

| cohort study |
A research study that compares a particular outcome (such as lung cancer) in groups of individuals who are alike in many ways but differ by a certain characteristic (for example, female nurses who smoke compared with those who do not smoke).
