1 · What the graph read from it

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.

2 · The registry

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

objectivesTo characterise the pattern of association between school academic performance and myopia shifts among Singaporean children.

methodsChildren from the Singapore Cohort Study of the Risk Factors for Myopia (SCORM) with available Grade 4 nationwide examination scores and ocular measurements were analysed (n = 721). Cycloplegic refraction and axial length (AL) were assessed at Grade 4 (age 10 years) and Grades 8-10 (aged 14-16 years). Multivariable models were used to examine associations between academic performance and annualised changes in spherical equivalent (SE) and AL, accounting for inter-eye correlation, with inclusion of both myopic and non-myopic children at baseline.

resultsEach 1-SD higher score was associated with a slightly more negative SE change (β = -0.04 D/year; 95% CI -0.062 to -0.011; p = 0.004) and greater axial elongation (β = 0.01 mm/year; 95% CI 0.004-0.021; p = 0.003) from Grade 4 to Grades 8-10. Findings were consistent across all subject-specific scores. LOWESS curves suggested possible non-linear patterns, with modestly steeper trends for SE and AL at Grades 8-10 and flatter patterns for their longitudinal changes at the upper end of the score distribution.

conclusionsHigher childhood academic performance was associated with faster myopic shift in both myopic and non-myopic children. Exploratory analyses suggested that SE and AL may not be uniformly distributed across the full range of academic performance.
