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

backgroundMyopia is a very common condition and a significant public health problem in China. The objective of the study was to explore the genetic influence on myopia in Mainland China school-aged children in Beijing.

methodsIn 2008, the data from 15,316 Chinese school students aged 6-18 years from 19 randomized schools in Beijing were analyzed to evaluate genetic influence on myopia in children. Heritability was calculated by mid-parent-offspring regression and parent-offspring regression.

resultsThe estimate of heritability was 0.30 (95% CI, 0.27-0.33) for refractive value (RV). The adjusted mean refractive error was -2.33D (95% CI, -2.45 to -2.21) in children with two myopic parents compared with -1.13D (95% CI, -1.78 to -1.08) in children with no parental myopia. The adjusted odds ratio (OR) was 2.83 (95% CI, 2.47-3.24) in children with two myopic parents compared with no parental myopia.

conclusionThe study found a strong association between parental history of myopia and genesis of myopia in the offspring even after adjusting for environmental factors.
