In managing chronic diseases, the role of social determinants like lifestyle and diet is crucial. A comprehensive strategy combining biomedical and lifestyle changes is necessary for optimal health. However, the complexity of evidence from varied study designs on lifestyle interventions poses a challenge to decision-making. To tackle this challenge, our work focused on leveraging large language model to construct a dataset primed for evidence triangulation. This approach automates the process of gathering and preparing evidence for analysis, thereby simplifying the integration of reliable insights and reducing the dependency on labor-intensive manual curation. Our approach, validated by expert evaluations, demonstrates significant utility, especially illustrated through a case study on reduced salt intake and its effect on blood pressure. This highlights the potential of leveraging large language models to enhance evidence-based decision-making in health care.

I confirm all relevant ethical guidelines have been followed, and any necessary IRB and/or ethics committee approvals have been obtained.

Yes

I confirm that all necessary patient/participant consent has been obtained and the appropriate institutional forms have been archived, and that any patient/participant/sample identifiers included were not known to anyone (e.g., hospital staff, patients or participants themselves) outside the research group so cannot be used to identify individuals.

Yes

I understand that all clinical trials and any other prospective interventional studies must be registered with an ICMJE-approved registry, such as ClinicalTrials.gov. I confirm that any such study reported in the manuscript has been registered and the trial registration ID is provided (note: if posting a prospective study registered retrospectively, please provide a statement in the trial ID field explaining why the study was not registered in advance).

Yes

I have followed all appropriate research reporting guidelines, such as any relevant EQUATOR Network research reporting checklist(s) and other pertinent material, if applicable.
