Trends in Plant-Based Diets among United States Adults, 1999-March 2020.
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 10 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
backgroundInterest in plant-based eating has increased alongside increased variety and availability of highly processed plant-based meat and dairy alternatives. The impact of the shifting commercial landscape and public interest in plant-based eating on dietary intake is unknown.
objectivesTo examine trends in the consumption and composition of plant-based diets in the United States adults.
methodsSerial cross-sectional data from the National Health and Nutrition Examination Survey were used to assess trends in the proportion of United States adults aged ≥20 y consuming a plant-based diet (defined as ≥50% total protein from plants on a 24-h dietary recall) from 1999-2000 to 2017-March 2020 (n = 51,698). Trends in processing level (percentage energy intake from ultraprocessed foods) and diet quality [Healthy Eating Index (HEI)-2020 scores] were assessed in the subset of adults consuming plant-based diets (n = 8327).
resultsThe proportion of United States adults consuming plant-based diets increased from 14.4% (95% CI: 12.9%, 16.0%) to 17.2% (95% confidence interval [CI]: 15.5%, 19.1%; P = 0.005 for trend). In all survey cycles, ultraprocessed foods accounted for the majority of energy intake, and ultraprocessed food intake in plant-based diets did not significantly change over time [50.7% kcal (95% CI: 47.3%, 54.1%) in 1999-2000 compared with 52.7% kcal (95% CI: 49.7%, 55.6%) in 2017-March 2020; P for trend = 0.34]. The quality of plant-based diets, measured by HEI-2020 scores, improved from 52.1 (95% CI: 49.7, 54.6) to 55.8 (95% CI: 54.1, 57.5; P for trend <0.001).
conclusionsBetween 1999 and March 2020, the proportion of United States adults consuming a plant-based diet increased. Among people consuming plant-based diets, ultraprocessed foods contributed most to energy intake and there was no sustained change in intake over time. The mean diet quality was low but improved modestly.
