Machine learning tools that assist the Systematic Review process. The central figure represents from the early to the late stages of the systematic review process described by the Cochrane Foundation (Higgins JPT et al., Cochrane Handbook for Systematic Reviews of Interventions version 6.3, Cochrane, 2022). The obtained ML tools were grouped into blocks depending on the covered SR step. Next to the tool names, the yellow symbol means the requirement of a payment licencing to access to the full version of the tool and the green symbol open-source availability. SR = Systematic Review, ML = Machine learning
