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

Central nervous system (CNS) involvement in hereditary transthyretin (TTR) amyloidosis has been described in patients whose disease course was modified by liver transplant. However, cognitive dysfunction has yet to be investigated in those patients. Moreover, CNS involvement in untreated patients or asymptomatic mutation carriers remains to be studied. A series of 340 carriers of the TTRVal30Met mutation (180 symptomatic and 160 asymptomatic) underwent a neuropsychological assessment, which included the Dementia Rating Scale-2 (DRS-2), auditory verbal learning test, semantic fluency, phonemic fluency, and trail making test. Cognitive deficits were identified at the individual level, after adjusting the neuropsychological test scores for demographic characteristics (sex, age, and education), based on large national normative data. The presence of cognitive dysfunction was determined by deficit in DRS-2 and/or multiple cognitive domains. Participants were also screened for depression based on a self-report questionnaire. The frequency of cognitive dysfunction was higher (p = 0.003) in symptomatic (9%) than in asymptomatic (2%) carriers. Among older carriers (≥ 50 years), the frequency of cognitive dysfunction was higher (p < 0.001) in symptomatic (36%) than asymptomatic (4%) individuals. Among younger participants (< 50 years), the frequency of cognitive dysfunction was not different (p = 0.631) between symptomatic patients (2%) and asymptomatic (1%) carriers. This cross-sectional study shows that cognitive dysfunction is part of the broad spectrum of clinical manifestations in older hereditary TTR amyloidosis patients with peripheral polyneuropathy, even in the early stages of the disease.
