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

In brains of individuals who had sustained repetitive head trauma, advanced pathologic tau protein in neurons and axons within temporal cortices followed patterns seen in homologous cortico-cortical connections in nonhuman primates. The relational Structural Model, which is based on the universal principle of the systematic variation of cortical laminar structure, has successfully predicted the relative laminar distribution of cortico-cortical connections based on the relative similarity/difference in laminar structure in pairs of linked areas. Here, the Structural Model successfully predicted the graded laminar distribution and density of pathologic tau in chronic traumatic encephalopathy and was validated by a computational progression model. By contrast, early and sporadic tau pathology in the depths of sulci in chronic traumatic encephalopathy followed local columnar connectivity rules. These findings support applicability of a theoretical model to unravel the direction and progression of tau pathology in neurodegeneration via cortical connection mechanisms. Cortical pathways converging on temporal cortices may help explain the inexorable spread of pathologic tau to widespread cortical areas accompanied by decline in emotional and cognitive processes in humans with repetitive head trauma.
