Observational studies are used frequently to address a wide range of clinical questions when randomized clinical trials are not feasible or practical. One of the powerful vascular research tools is the cohort study. The cohort study is a reliable observational study design in which individuals who share a common characteristic (a cohort) are followed over time and their outcomes are assessed at various intervals. This review focuses on the essential characteristics, design, implementation, bias, validity, and clinical significance of cohort studies and provides illustrative examples. A cohort study can be either a prospective or a retrospective study, depending on whether the outcome occurred before or after the enrollment of the cohort. Each type has its advantages and disadvantages. Confounding, selection, and information biases can all occur in cohort studies. Applications of the cohort study design include studying the natural history of a disease, describing a condition's frequency, and investigating multiple outcomes simultaneously.||URI:||https://ahro.austin.org.au/austinjspui/handle/1/31744||DOI:||10.1053/j.semvascsurg.2022.09.004||ORCID:||Journal:||Seminars in Vascular Surgery||Start page:||404||End page:||412||PubMed URL:||36414356||ISSN:||1558-4518||Type:||Journal Article||Subjects:||Vascular Surgical Procedures/adverse effects|
