[Conflicts of interest in scientific advisory panels].

Independence is crucial for the quality and credibility of scientific recommendations and guidelines. The composition of advisory committees requires a full understanding of the relationships and interests of prospective committee members. In addition to financial relationships, intellectual interests, professional interests, and reputation may also play a role.

Metabolic Age Based on the BBMRI-NL H-NMR Metabolomics Repository as Biomarker of Age-related Disease.

Background: The blood metabolome incorporates cues from the environment and the host's genetic background, potentially offering a holistic view of an individual's health status.

Methods: We have compiled a vast resource of proton nuclear magnetic resonance metabolomics and phenotypic data encompassing over 25 000 samples derived from 26 community and hospital-based cohorts.

Results: Using this resource, we constructed a metabolomics-based age predictor (metaboAge) to calculate an individual's biological age.
