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

Hereditary transthyretin amyloidosis (ATTRv) is a condition with adult onset, caused by mutation of the transthyretin (TTR) gene and characterized by extracellular deposition of amyloid fibrils in tissue, especially in the peripheral nervous system (PNS) and heart. PNS involvement leads to a rapidly progressive and disabling sensory-motor axonal neuropathy. Although awareness among neurologists increased in recent years thanks to new treatment options, ATTRv is frequently misdiagnosed, and thus a correct diagnosis can be delayed by several years. This review aims to draw the history and features of polyneuropathy in ATTRv based on pathological and electrophysiological correlates. We assessed original articles and case reports based on their relevance to ATTRv neuropathy and we included those appropriate for the scheme of this narrative review. Amyloid fibrils initially deposit in ganglia, causing an axonal neuropathy without amyloid deposits in distal segments (eg, sural nerve biopsy). Over time, amyloid fibrils spread along the nerves, leading to some demyelinating features in the context of severe axonal loss. This review highlights how the features of neuropathy change based on type of ATTRv (early vs late onset) and stage of disease.
