The 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 SeriesThis activity is part of a series.
