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

purposeTo assess for gammaD-crystallin (CRYGD) mutation in 2 Saudi patients with cerulean cataract and in a brother of one of the patients who had coralliform cataract.

methodsPatients and all of their available relatives underwent ophthalmic examination and subsequent sequencing of the candidate gene CRYGD.

resultsIn the first family, a 4-year-old boy with bilateral cerulean cataract and his 6-year-old brother with similar bluish lens discoloration but in a coralliform pattern were heterozygous for the p.P23T CRYGD mutation. Their father and 2 older brothers, all of whom underwent childhood cataract surgery, also harbored the mutation while the 2 asymptomatic immediate family members did not. In the second family, a 7-year-old girl with bilateral cerulean cataract was heterozygous for the same CRYGD mutation. Details of her family history were limited. The patients in the two families shared a common disease haplotype.

conclusionsThis first report of p.P23T CRYGD mutation underlying cerulean cataract in the Saudi population strongly supports the mutation's relation with the phenotype. Coralliform cataract can represent variable expressivity for the same mutation rather than a distinct entity.
