| Multicenter Study [Publication Type] Multicenter Study (PT) Work consisting of a controlled study executed by several cooperating institutions. | |
| Epidemiologic Studies Epidemiological Studies | Studies, Epidemiologic | Epidemiologic Study | Epidemiological Study | Studies, Epidemiological | Study, Epidemiologic | Study, Epidemiological Studies designed to examine associations, commonly, hypothesized causal relations. They are usually concerned with identifying or measuring the effects of risk factors or exposures. The common types of analytic study are CASE-CONTROL STUDIES; COHORT STUDIES; and CROSS-SECTIONAL STUDIES. | |
| Intervention Studies Intervention Study | Studies, Intervention | Study, Intervention Epidemiologic investigations designed to test a hypothesized cause-effect relation by modifying the supposed causal factor(s) in the study population. | |
| Epidemiologic Study Characteristics Characteristic, Epidemiologic Study | Characteristics, Epidemiologic Study | Epidemiologic Study Characteristic | Study Characteristic, Epidemiologic | Study Characteristics, Epidemiologic Types and formulations of studies used in epidemiological and clinical research. | |
| Retrospective Studies Retrospective Study | Studies, Retrospective | Study, Retrospective Studies used to test etiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past. The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons. | |

Latent subclinical infections and carrier states can thus be detected in addition to clinically overt cases. | |
