Retrospective review

see Retrospective Study.

The terms “retrospective review” and “retrospective study” are often used interchangeably to describe a type of study design. Both involve looking back at historical data to analyze outcomes or associations. In these types of studies, researchers do not intervene or manipulate variables; instead, they analyze data that has already been collected.

A retrospective study or retrospective review involves the collection and analysis of data that were collected in the past. Researchers may examine medical records, databases, or other sources of existing data to investigate relationships between variables or to assess outcomes over time.

So, in summary, when you encounter the terms “retrospective review” or “retrospective study,” they typically refer to the same type of study design – one that involves the retrospective analysis of existing data.
