Prevalence of visual impairment and associated factors among primary school children in Ambo Town, Ethiopia, 2021.
Article in SAGE open medicine, 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
Background: Visual impairment is a functional limitation of the eye(s) or the visual system manifested as reduced visual acuity. At least 2.2 billion people have visual impairment worldwide, and 90% of people with visual impairment have either preventable or treatable causes with cost-effective interventions. Objectives: To assess magnitude of visual impairment and associated factors among primary school children in Ambo Town, Ethiopia, in 2021. Methods: A cross-sectional study was conducted in selected primary schools of Ambo Town. A simple random sampling technique was used to select schools and study participants. Data were collected using an interviewer-administered structured questionnaire and entered into Epidata version 3.1 for analysis by using SPSS version 23. Binary logistic regression was adopted to identify statistically significant factors which were associated with visual impairment. The Hosmer-Lemeshow test was used to evaluate how well the logistic regression model fits to the data. Results: About 780 out of 838 primary school children were enrolled in the study, yielding a response rate of 93.07%. The estimated prevalence of visual impairment was 8.8% with 95% CI: 6.81-10.79. The main risk factor for visual impairment among primary school children were Students' grade level, exposure to mobile screen, family history of visual problems, and family awareness about the status of their child's eye problems were significantly associated with visual impairments (AOR = 2.375, 95% CI: 1.079-5.226; AOR = 2.44, 95% CI: 1.401-5.01; AOR = 2.41, 95% CI: 1.071-5.42; and AOR = 4.503, 95% CI: 2.12-9.55, respectively). Conclusion: A high prevalence of visual impairment was observed among primary school children. Attending higher grades, being exposed to mobile screen, and having a family history of visual problems were significantly associated with visual impairment.
