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
backgroundThe visual health of preschool children is of utmost importance in shaping the visual development during school-age years. The preschool period marks a critical phase for vision maturation, with vision impairments potentially leading to inattention, diminished academic performance, and psychological issues, thereby exerting profound impacts on children’s futures.
methodsUtilizing a random sampling approach, this study enrolled 4–6 years old preschoolers from a large kindergarten in the main city. A questionnaire, grounded in the “Student Health Status and Influencing Factors Survey (Student Version)” by the Chinese Center for Disease Control and Prevention, was employed to assess the multifaceted influence of genetics, eye usage patterns, outdoor activity habits, and dietary intake on myopia susceptibility. Screening myopia (noncycloplegic autorefraction) was utilized for vision assessments.
resultsOf the 388 valid questionnaires collected, a myopia detection rate of 25.7% was observed, with a significant age-related increase (OR = 4.591, P = 0.018). Notably, factors such as extended outdoor activity time (OR = 0.357, P = 0.005), adequate eye-to-book distance (OR = 0.179, P = 0.064), and proper finger-to-pen-tip distance (OR = 0.279, P = 0.029) correlated with reduced myopia risk. Conversely, insufficient pork liver intake was linked to heightened myopia risk (OR = 4.332, P = 0.001). In the 6 years old group, compared to the 3–5 years old group, myopia was influenced by diverse factors, including 1–2 h of outdoor activities (OR = 0.336, P = 0.009), electronic device usage (OR = 3.152, P = 0.032), and fried food consumption (OR = 4.210, P = 0.04).
conclusionsThese findings highlight the importance of genetic factors, eye usage habits, outdoor activities, and diet in the development of myopia. Consequently, preventing myopia is a long-term endeavor that necessitates the collaborative effort of multiple systems.
