Evaluating the diet quality of elderly Japanese using the Healthy Eating Index-2020.
Article in Asia Pacific journal of clinical nutrition, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 AND
objectivesGlobally, efforts are underway to evaluate foods and meals by their nutritional value. In Japan, however, there is no comprehensive system for evaluating overall diet quality. The aim of this study is to use the Healthy Eating Index (HEI)-2020, which is based on the American Dietary Guidelines, to evaluate the diet quality of independent elderly Japanese people to consider appropriate methods for evaluating the Japanese diet. METHODS AND STUDY
designThe subjects were 71 individuals aged 60 years or older who participated in a health examination. HEI-2020 was used to evaluate diet quality, with 13 components scored based on intake per energy unit. Associations of HEI-2020 scores with nutrient intake, food group intake, and dietary reference intakes (DRIs) for Japanese were analysed using statistical methods.
resultsThe median HEI-2020 score was 52/100 points. Among the components, the median score was the maximum for Saturated Fats and Added Sugars, but zero for Whole Grains and Refined Grains. The high-score group had significantly lower intake of saturated fatty acids and higher intake of dietary fiber, vitamin K, potassium, and magnesium. In comparison to DRIs, the high-score group had a significantly higher "% meeting the reference value" for several nutrients, including dietary fiber, magnesium, and potassium.
conclusionsThis study shows that the HEI-2020 can identify nutrients such as dietary fiber and minerals that are lacking in the Japanese population. However, for more effective assessment, there is a need to adjust the reference values to match the intake of Japanese people.
