Large data sources are frequently used for epidemiologic studies 1,2 because descriptive or case-control . There are three sources of information for exposure data: (1) Records (2) Information collected from individuals in the group. Source control and transmission reduction - Several studies support the use of masks to provide source control and reduce transmission in the community [252,260-270]. Selection Bias Examples Also occurs before subjects are identified for study Diagnostic or workup bias: Diagnoses (case selection) may be influenced by physician's knowledge of exposure Example: Case control study - outcome is pulmonary disease, exposure is smoking Radiologist aware of patient's smoking status when reading Epidemiology is the method used to find the causes of health outcomes and diseases in populations.In epidemiology, the patient is the community and individuals are viewed collectively.
