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

objectiveTo report the clinical, electroencephalographic, and neuroradiologic findings in a kindred with a novel insertion in the prion protein gene, PRNP.

designClinical description of a kindred.

settingMayo Clinic Alzheimer Disease Research Center (Rochester, Minnesota). SUBJECTS: Two pathologically confirmed cases and their relatives.

main outcome measuresClinical features, electroencephalographic patterns, magnetic resonance imaging abnormalities, genetic analyses, and neuropathologic features.

resultsThe proband was a woman with clinical and neuroimaging features of atypical frontotemporal dementia and ataxia. Generalized tonic-clonic seizures developed later in the disease course, and electroencephalography revealed spike and wave discharges but no periodic sharp-wave complexes. Her affected sister and father also exhibited frontotemporal dementia-like features, and both experienced generalized tonic-clonic seizures and gait ataxia late in the disease course. Genetic analyses in the proband identified a novel defect in PRNP, with 1 mutated allele carrying a 288-base pair insertion consisting of 12 octapeptide repeats. Neuropathologic examination of the proband and her sister revealed prion protein-positive plaques and widespread tau-positive tangles.

conclusionsThis kindred has a unique combination of clinical and neuropathologic features associated with the largest base pair insertion identified to date in PRNP and underscores the need to consider familial prion disease in the differential diagnosis of a familial frontotemporal dementia-like syndrome.
