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

backgroundThe SorLA protein, encoded by the Sortilin-related receptor 1 (SORL1) gene, is a major player in Alzheimer's disease (AD) pathophysiology. Functional studies demonstrated that SorLA deficiency results in increased production of Aβ peptide, and thus a higher risk of AD. SorLA can be subject to proteolytic shedding at the cell surface, leading to the release of the soluble ectodomain of the protein (sSorLA) in the extracellular space. Recently, we demonstrated that a large proportion (~25%) of rare SORL1 missense variants found in AD patients alter SorLA trafficking along the constitutive secretory pathway, resulting in reduced delivery of SorLA to the plasma membrane and thus a loss of function. Here, we aimed to determine if CSF levels of sSORLA in AD patients carrying SORL1 rare variants that impact or not the trafficking of the protein can be used as a novel biomarker to explore disrupted trafficking of SorLA protein in AD.

methodsA total of 151 participants were categorized into 5 study groups: controls without any neurodegenerative disease (n=30), patients suffering from Fronto-Temporal Lobar Degeneration (FTLD, n=34), AD patients not carrying a SORL1 rare variant (AD

resultsWe found significantly decreased levels of sSorLA in AD

conclusionsOur results suggest that differential levels of sSorLA in CSF could be used as a novel marker to explore disrupted trafficking of SorLA protein in Alzheimer disease. This could help solve some proportion of variants of uncertain significance in SORL1.
