The association between fruit and vegetable intake and the odds of asthma among children and adolescents.
Article in Journal of health, population, and nutrition, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
backgroundPrevious epidemiological studies on the correlation between fruit and vegetable consumption and asthma, the majority of them were conducted in developed countries, have led to conflicting results. This study aimed to examine the relationship between fruit and vegetable intake and the risk of asthma among a large sample of children and adolescents.
methodsThis cross-sectional study was conducted as part of the Global Asthma Network (GAN) on 7667 Iranian children and adolescents. Asthma and its related outcomes were measured using validated questionnaires. A food frequency method was used to assess the dietary intake. The association between fruit and vegetable intake and asthma and its related symptoms was examined using logistic regression.
resultsAfter adjustment for all possible confounding variables, no significant association was found between fruit and vegetable intake and the odds of medication use for asthma and asthma confirmed by a doctor. However, an inverse significant trend was found between fruits intake and current asthma. After adjusting for age, sex, BMI, and the use of television and computers, participants who regularly consumed fruit had a 37% lower likelihood of experiencing wheezing in the past 12 months (OR = 0.63; 95% CI: 0.42-0.94, P trend = 0.001) compared to those who never or only occasionally consumed fruit. Additionally, individuals who reported consuming vegetables most or all days had a 38% reduced chance of wheezing in the past 12 months (OR = 0.62; 95% CI: 0.48-0.80, P trend < 0.001) compared to participants with infrequent vegetable intake. Participants with regular fruit and vegetable intake combined (OR = 0.50; 95% CI: 0.31-0.82, P trend < 0.001) had a 50% lower likelihood of wheezing in the past 12 months in comparison with those who never or only occasionally fruits and vegetables combined consumers.
conclusionOur findings suggest that regular consumption of fruits and vegetables on most or all days has a protective effect against wheezing in the past 12 months. Future longitudinal studies should be conducted to confirm our findings.
