Visual perceptive functioning in Japanese schoolchildren born with very low birth weight.
Article in BMC pediatrics, 2025. 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
backgroundWe aimed to use the Wide-range Assessment of Vision-related Essential Skills (WAVES) to evaluate the visual perception of Japanese schoolchildren born weighing < 1500 g, who did not need support class and had a normal IQ score.
methodsThe very-low birth weight infant group (VLBWI group) included 38 (17 male, 21 female) first-grade elementary schoolchildren born between April 2009 and March 2013 at Osaka Medical College Hospital and Saiseikai Suita Hospital. The scores for the 10 subtests and 4 indices of WAVES were calculated for all participants and compared to the WAVES normative database of schoolchildren in the same grade (C group). We assessed whether clinical history was associated with WAVES score in the VLBWI group.
resultsCompared with the C group, the participants in the VLBWI group had significantly lower scores for form tracing (success and rate scores), figure-ground speed, discrimination accuracy, visual memory, copying, and the indices of WAVES, except for the eye-hand coordination general index. The scores for line tracing (ratio) and eye-hand coordination accuracy index were significantly lower in participants who were born at gestational age < 28 weeks than in those born at gestational age ≥ 28 weeks. Copying performance was significantly lower in participants with than without chronic lung disease.
conclusionThis is the first study to evaluate the visual perception of schoolchildren born weighing < 1500 g in Japan. We report lower scores of WAVES' subtests on processing speed in these children, implying they might have increased risk of poor school performance and learning disabilities.
