Planetary health diet index and low muscle mass in adults aged 20-60 years: exploratory evaluation of a dairy-upweighted outcome-specific adaptation.

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
Background: Increasing evidence indicates that the Planetary Health Diet Index (PHDI), proposed within the EAT-Lancet framework, not only supports environmental sustainability but also contributes to the prevention of various diseases. However, the rigorous restriction of animal-sourced proteins in the standard PHDI may overlook the heightened anabolic needs of aging populations. This study primarily aimed to evaluate the association between PHDI-US adherence and low muscle mass (LMM) and to compare this association with other commonly used dietary indices. As a secondary exploratory step, we examined whether an exploratory dairy-upweighted score, derived by multiplying the original PHDI-US total score by the observed dairy intake amount, might show a stronger association with LMM. Methods: Multivariable logistic regression and restricted cubic spline (RCS) models were used to evaluate the association between the Planetary Health Diet Index for the United States (PHDI-US) and low muscle mass (LMM). Random-forest feature-importance analysis was then used to identify the most influential dietary component within the PHDI-US and to derive a dairy-upweighted version of the score (PHDI-Dairy). We then examined the association between dairy intake and LMM in an independent Southern Chinese cohort. Results: In fully adjusted models, higher PHDI-US and Alternative Healthy Eating Index scores were associated with lower odds of LMM, whereas a higher Dietary Inflammatory Index score was associated with higher odds of LMM. Healthy Eating Index and Mediterranean Diet Index scores were not statistically significant in fully adjusted quartile analyses. In exploratory analyses, a dairy-upweighted score (PHDI-Dairy) showed a stronger inverse association with LMM than the original PHDI-US. In a separate hospital-based Southern Chinese cohort, higher dairy intake was associated with lower odds of LMM, providing supportive evidence for the dairy-related finding. Conclusion: PHDI-US was modestly associated with lower odds of LMM, and the exploratory dairy-upweighted score, PHDI-Dairy, showed a stronger inverse association with LMM.
