Systematic reviews rigorously compile all available data on a specific topic, helping researchers understand the state-of-the-art and avoid unnecessary duplication of studies and resources. From a clear scientific question as a starting point, it is essential to create a systematic search protocol, carefully distil the outputs obtained, and finally analyse and interpret the results derived. We will help you identify if your question has already been answered, if there is a niche to exploit, or if it needs to be refined in order to move forward with your next steps.
