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

backgroundAutosomal dominant radial drusen (ADRD), also termed Malattia Leventinese and Doyne honeycomb retinal dystrophy, causes early-onset vision loss because of mutation in EFEMP1. Drusen in an exceedingly rare ADRD human donor eye was compared with eyes affected with age-related macular degeneration (AMD). This study also elucidated whether variations in high-risk AMD genotypes modify phenotypic severity of ADRD.

methodsMorphologic and histochemical analyses of drusen in one ADRD donor and seven AMD donors. Evaluation of complement factor H (CFH) and ARMS2/HTRA1 alleles in a cohort of 25 subjects with ADRD.

resultsAutosomal dominant radial drusen had unique onion skin-like lamination but otherwise shared many compositional features with hard, nodular drusen and/or diffuse soft drusen with basal deposits. Autosomal dominant radial drusen also possessed collagen type IV, an extracellular matrix protein that is absent in age-related drusen. Antibodies directed against the membrane attack complex showed robust labeling of ADRD. Vitronectin and amyloid P were present in drusen of both types. High-risk alleles in the CFH and ARMS2/HTRA1 genes were not associated with increasing ADRD severity.

conclusionDrusen from ADRD and AMD exhibit overlap of some major constituents, but ADRD exhibit distinct alterations in the extracellular matrix that are absent in AMD.
