Multicomponent exercise interventions for cognitive function in patients with mild cognitive impairment: a summary of best evidence.

The evidence is drawn entirely from secondary sources (systematic reviews and meta-analyses), so conclusions depend on the quality of the original primary studies. The search was limited to Chinese and English publications, potentially excluding relevant evidence from other languages. There is insufficient detail on the optimal ratio of exercise components or specific guidelines for individualized adjustments. The review does not report the total number of participants across the included studies, limiting assessment of statistical power. Heterogeneity in intervention protocols across the included studies may affect the reliability of specific dosage recommendations.

The study was funded by the Science and Technology Program of the Joint Fund of Scientific Research for the Public Hospitals of Inner Mongolia Academy of Medical Sciences. The authors declared financial support for the work.

Do not interpret the positive findings as proof of efficacy from primary trials. This review synthesizes secondary evidence, and the authors note that the conclusions are constrained by the methodological quality of the cited reviews and potential publication bias. The recommended dosage is a synthesis of expert opinion and review data, not a result of a single definitive trial.
