CRB1 maculopathy presenting as fenestrated sheen macular dystrophy with 15-year follow-up.
Article in Documenta ophthalmologica. Advances in ophthalmology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
introductionWe present two patients, the proband and the affected sibling, with biallelic CRB1 mutations leading to a macular dystrophy. CASE PRESENTATION: We present two patients, the proband and the affected sibling, with biallelic CRB1 mutations leading to a macular dystrophy. With 15 years of follow-up for the proband, we illustrate the natural history of CRB1 maculopathy based on clinical examination, multimodal imaging, and electrophysiology. In addition, we demonstrate the wide phenotypic spectrum of the condition with the affected sister harboring the same variants but with much milder phenotypic manifestations.
conclusionIn addition to a previously described pathogenic variant, Ile167_Gly169del, one pathogenic missense variant in CRB1, Lys801Ter, not previously associated with macular dystrophy, is reported here. While CRB1 mutations have been more commonly described in retinitis pigmentosa (RP) and Leber congenital amaurosis (LCA), we demonstrate that mutations in CRB1 can cause a maculopathy with initial features similar to fenestrated sheen macular dystrophy (FSMD) that later evolves into severe macular atrophy.
