However, it remains unclear which intervention measure is the most effective. The objective of this study is to compare and rank the influences of various non-pharmacological interventions on the cognitive function of patients with type 2 diabetes and mild cognitive impairment.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sec002\">\n<jats:title>Methods<\/jats:title>\n<jats:p>Eight databases from the establishment of the database to November 2024 were retrieved.

The SUCRA ranking revealed that in terms of improving the MoCA scores, the comprehensive intervention (SUCRA 76.9%), cognitive training (SUCRA 63.3%), and TCM therapy (SUCRA 57.9%) were the top 3 preferred treatment measures; for improving the MMSE scores, exercise therapy (SUCRA 78.0%) and cognitive training (SUCRA 73.8%) were the preferred treatment measures.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sec004\">\n<jats:title>Conclusion<\/jats:title>\n<jats:p>The current evidence indicates that cognitive training, exercise therapy, and TCM therapy might be relatively effective intervention approaches for improving the cognitive function of patients with type 2 diabetes mellitus (T2DM) accompanied by mild cognitive impairment (MCI), and cognitive training could potentially be the most efficacious non-pharmacological treatment method. Constrained by the quantity and quality of the studies, more high-quality research is still required in the future to further validate this
