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

introductionHippocampal subfields are vulnerable to the transactive response DNA-binding protein of 43 kDa (TDP-43) and tau in primary age-related tauopathy (PART). Geometry-based morphometric analysis can improve the detection of structural changes in the hippocampus.

methodsForty-seven cases of autopsy-confirmed PART without TDP-43 and 19 cases of PART with TDP-43 underwent antemortem magnetic resonance imaging (MRI) hippocampal segmentation and shape analysis. A separate cohort of 16 younger healthy individuals (YHIs) was included as a reference group. Hippocampal shape was analyzed in Python with non-parametric cluster permutation testing.

resultsPART(TDP+) group exhibited thinner left subiculum and CA1, with curvature deformations in left CA1 and CA2/3, relative to PART(TDP-). Both PART groups showed right-sided predominance of thinning in presubiculum and subiculum, as well as curvature deformations in right presubiculum, subiculum, and CA1 when compared to YHIs. DISCUSSION: Geometry-based analysis showed different patterns of hippocampal thinning and curvature associated with PART(TDP+) compared to PART(TDP-).
