Claim by claim

A source study was identified, but the study's evidence could not be prepared for claim assessment. The claims below have not been assessed.

Claim 1 of 6Not checkedResearchers examined whether a 67-metabolite plasma signature of Mediterranean diet adherence is associated with long-term all-cause and cause-specific mortality and whether the association can be replicated across independent cohorts.View evidenceHide evidence

Not checked

A source study was identified, but the evidence comparison for this claim was not completed. No verdict has been assigned.

Claim 2 of 6Not checkedIn the PREDIMED randomized nutritional intervention trial, participants with higher baseline metabolomic signature scores generally showed better adherence to the Mediterranean diet and were less likely to smoke or have type 2 diabetes.View evidenceHide evidence

Not checked

A source study was identified, but the evidence comparison for this claim was not completed. No verdict has been assigned.

Claim 3 of 6Not checkedIn PREDIMED, people in the highest third of signature scores had a 23% lower relative hazard of death than those in the lowest third, and each standard deviation increase in the signature was associated with a 19% lower relative hazard of death.View evidenceHide evidence

As stated23% lower relative hazard of death; 19% lower relative hazard per SD increase

Not checked

A source study was identified, but the evidence comparison for this claim was not completed. No verdict has been assigned.

Claim 4 of 6Not checkedThe 1-year signature in PREDIMED was also associated with lower all-cause and cardiovascular mortality, while the association with cancer mortality was not statistically significant.View evidenceHide evidence

Not checked

A source study was identified, but the evidence comparison for this claim was not completed. No verdict has been assigned.

Claim 5 of 6Not checkedThe findings were independently replicated in 12,704 participants from the Nurses’ Health Studies and the Health Professionals Follow-up Study, where the highest fifth of signature scores had a 23% lower relative hazard of death than the lowest fifth.View evidenceHide evidence

Claim 6 of 6Not checkedThe article says the observational analyses do not establish that increasing the score or changing diet directly reduces mortality.View evidenceHide evidence
