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
Introduction: Cardiovascular diseases (CVDs) represent a significant global public health burden, accounting for approximately 31% of annual deaths worldwide. Diet quality and sociodemographic factors are recognized as critical determinants influencing cardiovascular risk, particularly among young adults. University students are considered a vulnerable population due to rapid lifestyle transitions that may affect long-term health outcomes. This study aimed to analyze the associations between dietary patterns, sociodemographic factors, and cardiovascular health indicators in Ecuadorian university students. Methods: A cross-sectional study was conducted between 2022 and 2023 among 404 students from the State University of Milagro (UNEMI) and the Polytechnic School of Chimborazo (ESPOCH). Data on sociodemographic variables, dietary intake, and cardiovascular biomarkers were collected using structured interviews, clinical measurements, and blood analyses. Dietary intake was assessed using a 24-hour recall and a food frequency questionnaire adapted from the Block Screening Questionnaire. Cardiovascular health indicators included triglycerides, LDL and HDL cholesterol, systolic and diastolic blood pressure, and glucose levels. Associations between diet, sociodemographic factors, and cardiovascular outcomes were analyzed using one-way ANOVA, stratified by sex, with effect size estimation (η²) and Bonferroni corrections for multiple comparisons. Results: Among the participants (58.3% women, 41.7% men, mean age = 23.3 ± 4.4 years), 22% reported a very high-fat diet, whereas only 2% followed a nutrient-rich diet. Women with a very high-fat diet exhibited significantly higher triglyceride levels (mean = 189.6 mg/dL) compared to those with a low-fat diet (mean = 132.4 mg/dL, Discussion and conclusions: This study demonstrates significant associations between dietary quality, sociodemographic background, and cardiovascular health among Ecuadorian university students. High-fat diets were linked to adverse lipid profiles and increased blood pressure, while nutrient-rich diets showed protective effects, especially among women. Regional and familial origins influenced cardiovascular risk markers, underscoring the relevance of socioeconomic and environmental determinants. Public health strategies should target dietary education, nutritional interventions, and region-specific policies to mitigate cardiovascular risk in young adult populations. Future research should adopt longitudinal and multivariable models to strengthen causal inferences and validate observed associations.
