Fruit and Vegetable Intake Patterns, Kidney Failure, and Mortality in Adults with and without Chronic Kidney Disease in the United States.
Article in The Journal of nutrition, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled 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.
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
backgroundFruits and vegetables (F&Vs) are vital components of healthy diets but may be restricted in chronic kidney disease (CKD) to avoid high-potassium intake. We previously generated F&V patterns for patients in the National Health and Nutrition Examination Survey (NHANES) and demonstrated an increased prevalence of the overall low-intake pattern in patients with CKD.
objectiveTo evaluate the association of F&V patterns (overall low intake, high unprocessed, moderate processed, and high ultraprocessed) with the risk of kidney failure and its composite with death.
methodsAdults in NHANES III with valid dietary data and longitudinal follow-up for kidney failure and death were included. F&V patterns were identified using 24-h dietary recalls and latent class analysis, yielding 4 patterns. Cox models were used to evaluate the prospective association between each pattern and hazard of kidney failure or a composite of kidney failure or death over ≤20 y. Models were adjusted for demographics and select comorbidities and weighted for the complex survey design. Secondary analyses evaluated serum carotenoids as objective biomarkers of F&V intake.
resultsAmong 16,726 eligible participants in NHANES III, F&V consumption consistent with the high-ultraprocessed pattern associated with the highest risk of kidney failure after demographic and comorbidity adjustment, but attenuated with adjustment for kidney function. The high unprocessed pattern associated with the lowest adjusted risk of death or kidney failure combined [hazard ratio (HR): 0.73; 95% confidence interval (CI): 0.65, 0.81 relative to overall low intake]. Higher-serum carotenoids were associated with a lower adjusted risk of death or kidney failure combined (HR: 0.57; 95% CI: 0.49, 0.65 for quartile 4 compared with quartile 1). Results were similar in patients with CKD at baseline.
conclusionsHigher intake of unprocessed F&Vs was associated with better outcomes in the general population and patients with CKD. Results emphasize the need to safely improve F&V intake in CKD.
