How Do Retrospective Analyses Differ from Prospective Studies?
The key difference between retrospective and prospective studies lies in their approach to data collection. Retrospective studies analyze past data, while prospective studies plan and collect data going forward. Retrospective analyses can provide quick insights, but they may be limited by the quality and completeness of the historical data. Prospective studies, on the other hand, allow for more controlled and systematic data collection but require more time and resources.
