Television-watching in the early years of life and the association with parents' concerns about decreased visual acuity in their elementary school-aged child: results of a nationwide population-based longitudinal survey of Japan.
Article in Japanese journal of ophthalmology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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 study the association between television-watching in the earlier years of life and subsequent parents' concerns about decreased visual acuity in their elementary school-aged child. STUDY
designPopulation-based longitudinal cohort.
methodsTelevision-watching and its daily duration, as the main exposure, and parents' concerns for their child's decreased visual acuity during the school years, as the main outcome, were picked up from yearly questionnaires performed for the Longitudinal Survey of Newborns in the Twenty-First Century involving all babies born in Japan during either of two periods: between January 10 and 17, 2001 or between July 10 and 17, 2001 (N = 47,015).
resultsTelevision-/video-watching as the main form of play of children at the ages of 1.5 years and 2.5 years was significantly associated with parents' concerns for their child's decreased visual acuity raised once or more in six surveys conducted between the ages of 7 and 12 years (odds ratio, 1.1 and 1.09; 95% CI 1.05-1.15 and 1.04-1.14, respectively). The association remained significant after adjustment for confounding variables, including child's sex, preterm birth, multiple birth, mother's age at delivery, mother's and father's education, and residential area. Longer daily duration of television-watching at 2.5 years was significantly associated with concerns for the child's decreased visual acuity between the ages of 7 and 12 years, but not at the ages of 3.5, 4.5, and 5.5 years. The association remained significant in a sensitivity analysis of 28,820 children who participated in all six surveys.
conclusionsLonger daily exposure to television in children in the earlier years of life was associated with parents' subsequent concerns about decreased visual acuity in their elementary school-aged child.
