High body mass index with the risk of allergic conjunctivitis in children: a case-control study in Southwest China.
Article in BMC ophthalmology, 2024. 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
purposeTo assess the correlation of body mass index (BMI), diet and lifestyle with allergic conjunctivitis (AC) in children.
methodsThis prospective case-control study included 105 children with AC and 105 age- and sex-matched children with no AC. Clinical data were collected, including BMI, dietary habits, physical activity, and sleep time. Multivariate regression analysis was used to analyze the risk factors for AC.
resultsDietary habits including vitamin A supplement use (χ2 = 0.00; P = 1.00), the consumption of sweet food (χ2 = 6.70; P = 0.08), fast food (χ2 = 3.74; P = 0.29), beverages (χ2 = 1.17; P = 0.76), and seafood and fish (χ2 = 6.15; P = 0.10) and snacking before sleep (χ2 = 2.23; P = 0.53), were not associated with AC. There were significant differences in physical activity (χ2 = 12.64; P < 0.01) between the children with AC and healthy children. Physical activity of less than 1 h per day is more found among AC and more than 2 h of exercise per day is more found in healthy children. There were no differences in sleep duration (χ2 = 5.39; P = 0.07). Multivariate regression analysis revealed that a high BMI (overweight and obesity) (OR = 3.05; 95% CI: 1.30-7.20; P = 0.01) was a significant risk factor for AC. The consumption of fish oil supplements (OR = 0.38; 95% CI: 0.17-0.81; P = 0.01) and having been breastfed (OR = 0.34; 95% CI: 0.16-0.72; p = 0.005) were protective factors against AC.
conclusionA high BMI (overweight and obesity) can increase the incidence of AC. Breastfeeding and dietary supplementation with fish oil are recommended for children susceptible to AC.
