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

Mutations in MAPT, the tau gene, give rise to frontotemporal dementia and parkinsonism linked to chromosome 17 (FTDP-17), with abundant filamentous tau inclusions in brain cells. Mutations that encode missense variants of residue P301 are the most common and result in the formation of filamentous inclusions made of mutant four-repeat tau. Here we report the cryo-electron microscopy structures of tau filaments from five individuals belonging to three different families with mutation P301L and from one individual from a family with mutation P301T. A distinct three-lobed tau fold resembling the two-layered fold of Pick's disease was present in the individuals with P301L tau. Two different tau folds were found in the individual with mutation P301T, the less abundant of which was a variant of the three-lobed fold. The major P301T tau fold was V-shaped, with partial similarity to the four-layered tau folds of corticobasal degeneration and argyrophilic grain disease.
