Article in American journal of ophthalmology case reports, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT05537220 (NAC Attack, A Phase III, Multicenter, Randomized, Parallel, Double Masked, Placebo-Controlled Study Evaluating the Efficacy and Safety of Oral N-Acetylcysteine in Patients With Retinitis Pigmentosa), which is not on this map. Cited by 6 papers.

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.

Abstract

purposeTo report a severe phenotype of retinitis pigmentosa associated with novel mutations in OBSERVATIONS: Six siblings, age range 50-75 years old, were examined using optical coherence tomography and fundus autofluorescene, electroretinogram testing, Goldman visual field testing, and genetic testing using next generation sequencing.In four affected siblings, two novel compound heterozygous variants in CONCLUSIONS AND IMPORTANCE: This is the first report of a 12bp in-frame duplication and a missense variant (in compound heterozygous status) in
