Activity OverviewThe creation of the Rheum4Science program grew out of the conviction that teaching science is important for rheumatologists in training and that adult learners benefit from a variety of resources and formats. Rheum4Science interactive modules teach the underlying immunology and clinical research methodology necessary for the knowledgeable practice of rheumatology. This activity focuses on cohort studies, a type of observational study.  Learn about the defining strengths and limitations of cohort studies and how to apply the results of a cohort study to patient scenarios. Rheum4Science Series This activity is part of a series. See the other activities in the series below.

This activity may also be of interest to medical students, residents, practicing rheumatologists, and other rheumatology health care providers interested in strengthening their understanding of basic scientific principles and clinical research methodology relevant to the field of rheumatology.  Learning ObjectivesUpon completion of this activity, participants should be able to:Recognize a cohort studyDelineate the strengths and limitations of a cohort studyIdentify clinical questions that could be best answered using a cohort studyRecognize potential pitfalls encountered in cohort studies, and strategies to address theseAccurately interpret analytic approaches used in cohort studiesApply the results of a cohort study to patient scenariosCE & MOC InformationThis activity is not eligible for CME/MOC.Acknowledgement of Commercial SupportNo commercial support was provided for this activity.Educational Activity PoliciesSee ACR educational activity policies, including the online enduring activity refund policy.
