PICO is a popular framework for formulating clinical questions, especially those relating to therapy (or intervention) effectiveness. It’s used to develop a well-built clinical question to aid in creating a search strategy. It helps identify searchable aspects of a situation in which a patient or population has a certain condition, and the outcome of interest is related to a therapy or intervention.
