Planetary health diet index and risk of mortality and cardiovascular disease: evidence from the health and retirement study.
Article in Nutrition journal, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe EAT-Lancet Commission proposed the Planetary Health Diet to improve both human and planetary health. Evidence among older adults on its association with mortality and cardiovascular disease (CVD) remains limited. We therefore examined associations of the Planetary Health Diet Index (PHDI) with risks of all-cause mortality and CVD in a representative sample of U.S. middle-aged and older adults.
methodsThis cohort study used data from the U.S. Health and Retirement Study (HRS; 2012–2018) with dietary intake data from the 2013 Health Care and Nutrition Study (HCNS). Adherence to the PHDI was computed from 24-hour dietary recalls across 15 food groups (score range 0–140). All-cause mortality was ascertained via household surveys, and incident cardiovascular disease (CVD) was identified by self-reported physician-diagnosed heart disease. Cox proportional hazards models estimated hazard ratios (HRs) and 95% confidence intervals (CIs) for the association between quintiles of PHDI and risks of mortality and CVD, adjusting for demographic, lifestyle, and health-related covariates, including total energy intake.
resultsThe total cohort included 7,873 participants (58.83% women; mean age 66.72 years) for the mortality analysis, and the sub-cohort included 5,454 participants (60.80% women; mean age 64.65 years) for the cardiovascular disease analysis. Higher PHDI adherence was associated with lower risks of total mortality. Participants in the highest PHDI quintile had a 59% lower risk of total mortality compared with those in the lowest quintile (HRs: 0.41; 95% CI: 0.32, 0.53). Each 1 SD increase in PHDI was associated with a 25% reduction in all-cause mortality (HRs: 0.75; 95% CI: 0.69, 0.81). PHDI was also inversely associated with CVD risk (HRs: 0.72; 95% CI: 0.58, 0.91).
conclusionsIn this cohort of U.S. older adults, higher adherence to the PHDI was associated with lower risks of all-cause mortality and cardiovascular disease.
