CRF (Case Report Form) is a standard tool used in clinical trials to collect patient data. Think of it as a detailed questionnaire or form that keeps track of everything that happens to a patient during a clinical trial. It's like a patient's diary that researchers use to record important information such as symptoms, test results, and medications. These forms can be paper-based (pCRF) or electronic (eCRF), though most modern clinical trials use electronic versions. This is one of the most important tools in clinical research because it helps maintain data quality and ensures that studies follow proper guidelines.
