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

Frontotemporal lobar degeneration with TDP-43 inclusions (FTLD-TDP) can typically be categorized into one of four distinct histopathologic patterns of TDP-43 pathology, types A to D. The strength of this histopathologic classification lies in the association between FTLD-TDP subtypes and various clinical and genetic features of disease. Seven cases of FTLD-TDP were identified here which were difficult to classify based on existing pathologic criteria. Distinct features common to these cases included TDP-43 aggregates over a wide neuroanatomic distribution comprised of granulofilamentous neuronal inclusions, abundant grains, and oligodendroglial inclusions. TDP-43 aggregates were phosphorylated and associated with loss of normal nuclear TDP-43 protein (nuclear clearance) but were negative for ubiquitin. Biochemical analysis confirmed the presence of insoluble and phosphorylated TDP-43 and also revealed a distinct pattern of TDP-43 C-terminal fragments relative to other FTLD-TDP subtypes. Finally, these cases were uniformly associated with a very rapid clinical course culminating in death within ~3 years of disease onset. We suggest that these cases may represent a unique clinicopathologic subtype of FTLD-TDP which we provisionally call "type E." The immature appearance of TDP-43 aggregates, widespread distribution, uniform biochemical profile and rapid clinical course highlights the clinical and pathologic variability within FTLD-TDP, and raises the possibility that type E neuropathology is the sequelae of a particularly virulent strain of TDP-43 proteinopathy.
