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 report an unusual presentation of posterior polymorphous corneal dystrophy (PPCD) associated with band keratopathy, iridocorneal adhesions, heterochromia, keratoconus, and confocal microscopic findings suggestive of iridocorneal endothelial syndrome.

methodsConfocal microscopy, corneal topography, electroretinography, and genetic analysis were performed in the proband and his siblings.

resultsA 23-year-old man presented with decreased vision in both eyes over 9 months. Examination revealed bilateral alterations in corneal endothelial mosaic with corneal edema and beaten metal appearance in the right eye and cystoid endothelial opacities in the left eye. Marked heterochromia, band keratopathy, and broad peripheral anterior synechiae were present in both eyes. Topographic features of keratoconus were noted. Electroretinography did not detect abnormal retinal function, as has been described with PPCD associated with VSX1 mutations. Diagnosis of PPCD was postulated on the basis of the examination of 3 of proband's brothers by confocal microscopy. Genetic analysis of 3 known PPCD genes, VSX1, COL8A2, and TCF8, did not detect any mutations.

conclusionsIn severe cases, PPCD can resemble iridocorneal endothelial syndromes in both clinical appearance and imaging studies (confocal microscopy). There was a strong genetic phenotypic penetrance in the family, which was essential in the diagnostic decision making. A yet undetermined genotype is contributing to this unusual PPCD phenotype.
