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 impact of COVID-19 on refractive amblyopia risk factors (rARFs), among 5-year-old children in Israel.
methodsWe conducted a nationwide, community-based cross-sectional study to evaluate and compare trends in refractive amblyopia risk factors (rARFs) in more than 100,000 children aged 5 years, from urban kindergarten in Israel. The study was conducted from 2013 to 2023, using the PlusOptiX S12 autorefractor, a photo-screening device, to collect refractive measurements. The main outcome was the annual prevalence of rARFs across the ten-year study period.
resultsOverall, 101,626, 5 year-old children were included. The prevalence of rARFs declined from 11.4% (164/1445 children) in 2013 to 6.8% (476/6964 children) by 2023, with significant decrease observed during the post-COVID period. The prevalence of children with one rARF decreased from 9.0% to 5.6%, with corresponding reductions in those with two (1.6% to 1.0%) and three risk factors (0.8% to 0.2%). Analysis of each rARFs showed a shift in refractive patterns following COVID-19, with myopia increasing relative to the pre-COVID average, while anisometropia and astigmatism declined, and hyperopia showed a non-significant decrease.
conclusionWe observed a decrease in the prevalence of refractive amblyopia risk factors in an unscreened population of children in urban kindergartens over the past decade. Hyperopia, anisometropia, and astigmatism showed reductions during the post-COVID-19 period, while the myopia risk factor increased. These trends may reflect advances in diagnostic technology, greater public awareness, and the implementation of early vision screening, underscoring their importance.
