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
purposeFew studies of vision screening in school-aged children were reported in Tibetan Plateau. We herein summarize the results of a mandatory vision screening conducted in young children in the Tibetan Plateau of Southwest China.
methodsThe Lhasa Childhood vision Screening (LCVS) performed uncorrected distant visual acuity (UCVA) test on primary school students in urban Lhasa from July to September 2019. Pin-hole corrected VA (PCVA) was obtained for individuals with the UCVA less than 20/25. Decreased VA was defined for UCVA based on the American Academy of Pediatrics guidelines 2016 (UCVA < 20/32 for over 60 months). Visual impairment (VI), Mild VI, and moderate VI to blindness, defined as a PCVA less than 20/40, less than 20/40 to 20/63 and less than 20/63 in the better eye, respectively.
resultsOverall, 34,848 children aged 9.03 ± 1.87 years fulfilled the screening with a response rate of 98.5%. 18,412 (52.8%) of the participants were males, and 30,531(87.6%) were Tibetan. The prevalence of decreased VA, VI, Mild VI, and moderate VI to blindness was 35.6%, 4.4%, 3.5%, and 1.0%, respectively. The prevalence of decreased VA in grade 1-6 students was 28.8%, 20.8%, 26.9%, 40.7%, 50.8%, 59.5%, respectively. The prevalence of VI in grade 1 to 6 students was 1.5%, 1.4%, 2.4%, 5.6%, 7.7% and 9.9%, respectively.
conclusionThis study documented a relatively low prevalence of decreased VA and VI in Tibetan primary school students than other urban populations in China. An increasing trend of poor vision with grades was found.
