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

backgroundHereditary transthyretin amyloidosis (hATTR) is associated with significant morbidity and mortality. Early diagnosis and treatment are essential to improve patient's outcome. Carpal tunnel syndrome (CTS) is a common complication of hATTR amyloidosis. However, because CTS is also common in the general population, we wanted to assess whether CTS, when associated with systemic manifestations, could help direct physicians to screen for TTR gene mutation and early diagnosis.

methodsWe reviewed the charts and interviewed the patients with hATTR seen between 2017 and 2018. We noted the details of CTS diagnosis, treatment, and other systemic features of the disease.

resultsSeventeen of the 23 patients studied had CTS. CTS was the first manifestation of the disease in 10 of 17 patients. On average, CTS symptoms occurred 10.4 years before their diagnosis of hATTR amyloidosis. In 6 of 10 patients with CTS, the following systemic symptoms were present as the first manifestation: erectile dysfunction, dysautonomia, polyneuropathy, exercise intolerance, and gastrointestinal and ocular symptoms.

conclusionCTS occurs in most patients with hATTR amyloidosis and frequently precedes the hATTR diagnosis. Most patients with CTS preceding hATTR diagnosis have systemic features. Recognizing systemic features at the time of CTS presentation may help in early diagnosis of hATTR amyloidosis.
