Trajectories of plant-based diet indices and the associated risk of hypertension among Chinese adults: a cohort study based on the China Health and Nutrition Survey 2004-2015.
Article in Nutrition journal, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
backgroundPlant-based diets have been found to be associated with hypertension. Dietary intake is a dynamic and changing process that can be better characterized by trajectories of dietary indices. However, the associations between plant-based diet trajectories and hypertension over time remained unknown.
methodsWe used data from the China Health and Nutrition Survey 2004-2015 to analyze a cohort of Chinese adults ≥ 18 years of age who had no hypertension at baseline. Plant-based diets were measured by an overall plant-based diet index (PDI), healthful plant-based diet index (hPDI), and unhealthful plant-based diet index (uPDI) based on three 24-hour recalls. Trajectories of PDI, hPDI, and uPDI (2004 to 2011) were identified using group-based trajectory modeling. The associations between trajectories of PDIs and the risk of new-onset hypertension were estimated using Cox proportional hazard models.
resultsWe identified three trajectories for PDI, two for hPDI, and four for uPDI among the 2853 participants with a mean follow-up of 9.6 years. Compared with the PDI "low and stable" class, the PDI "high and decreasing" class had a 23% decreased risk (HR: 0.77; 95% CI: 0.62-0.95) of hypertension. There was no significant association with PDI "low and increasing" class. Compared with the hPDI "low and stable" class, the hPDI "high and stable" class had a 24% decreased risk (HR: 0.76; 95%CI: 0.64-0.91). For uPDI trajectories, compared with the "low and decreasing" class, the "high and increasing," "high and stable," and "low and increasing" classes had increased risks of 43% (HR: 1.43; 95% CI: 1.06-1.94), 77% (HR: 1.77; 95% CI: 1.26-2.49), and 72% (HR: 1.72; 95% CI: 1.26-2.33), respectively.
conclusionsThis study underscores the importance of maintaining high intakes of healthful plant-based diets and low intakes of unhealthful plant-based diets overtime for hypertension prevention.
