Description: A systematic review is a methodical evaluation of existing research to inform model development and diffusion strategies. This approach involves the collection, analysis, and synthesis of previous studies on a specific topic, using rigorous and predefined methods. Systematic reviews are fundamental in scientific research as they allow for the identification of patterns, trends, and gaps in current knowledge. Through a structured process, the aim is to minimize biases and ensure that the results are representative and reliable. This type of review not only involves data collection but also includes a critical assessment of the quality of the included studies, providing a solid foundation for informed decision-making. In the context of model diffusion, systematic reviews are essential for understanding how different approaches have been implemented and adapted across various populations and contexts, which in turn can guide the development of more effective strategies. In summary, a systematic review is a powerful tool that helps synthesize existing knowledge and inform future practices in research and model application.
