1 · What the graph read from it

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.

2 · The registry

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

Vegetarian diets are increasingly popular worldwide, but their impact on healthy aging in older adults remains unclear. This study examined the association between vegetarian diets and healthy aging among 2,888 healthy older Chinese adults from the Chinese Longitudinal Healthy Longevity Survey. Dietary patterns (vegan, ovo-vegetarian, pesco-vegetarian, omnivorous) were derived from a simplified non-quantitative food frequency questionnaire. Over a median follow-up of 6 years, after accounting for sociodemographic and lifestyle factors, vegetarians had lower odds of achieving healthy aging compared to omnivores (adjusted OR = 0.65, 95% CI: 0.47-0.89), with consistent results across sensitivity analyses and individual health components. Additionally, the health effects of vegetarian diets may vary depending on diet quality, with vegetarians of higher diet quality not significantly differing in terms of overall healthy aging and individual outcomes when compared to omnivores. Accordingly, this finding highlights modest inclusion of animal-based foods may improve the overall health status of healthy older adults.
