Vegetarian dietary patterns are not associated with lower odds of noncommunicable diseases among patients presenting to a tertiary care center in North India: a cross-sectional survey.
Article in Clinical nutrition research, 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
objectiveNoncommunicable diseases (NCDs) present a huge global burden, accounting for approximately 7.3 trillion cases and 43.8 million deaths in 2021. In India, 68% of all deaths are caused by NCDs. Carbohydrate intake has been associated with NCD development. Standard Indian diets mainly comprise carbohydrates. In this study, we aimed to analyze the association of vegetarian versus omnivorous diets with the odds of developing NCDs in patients visiting the emergency department.
methodsOver 18 months, a cross-sectional epidemiological survey-based study was conducted among patients aged >18 years presenting to our department with documented comorbid conditions (e.g., diabetes mellitus [DM], hypertension, heart disease, hypothyroidism, Alzheimer disease, and cancer). These patients completed a 32-item questionnaire survey regarding dietary and lifestyle choices. Associations between comorbidity status and dietary variables were evaluated by bivariate analysis. Additionally, unadjusted odds ratio (OR) and adjusted OR for DM, hypertension, and heart disease were calculated.
resultsThis study included 11,011 patients, of which 55.31% were males and 68.91% were >55 years old. Furthermore, 65.87% were vegetarians, whereas 28.97% were omnivores. Hypertension, DM, and heart disease were found in 62.6%, 49.9% and 26.0%, respectively, while 58% had combinations of NCDs. Adjusted for age, sex, smoking, sugar, alcohol, exercise, and packaged food, OR (omnivore vs. vegetarian) was 0.94 (95% confidence interval [CI], 0.86-1.03; P=0.180), 0.91 (95% CI, 0.83-1.00; P=0.052) and 1.02 (95% CI, 0.92-1.13; P=0.690) for DM, hypertension, and heart disease, respectively.
conclusionMost patients with NCDs followed a vegetarian dietary pattern, which was not associated with lower odds of developing NCDs.
