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

The hippocampus supports many facets of cognition, including learning, memory, and emotional processing. Anatomically, the hippocampus runs along a longitudinal axis, posterior to anterior in primates. The structure, function, and connectivity of the hippocampus vary along this axis. In human hippocampus, longitudinal functional heterogeneity remains an active area of investigation, and structural heterogeneity has not been described. To understand the cellular and molecular diversity along the hippocampal long axis in human brain and define molecular signatures corresponding to functional domains, we performed single-nuclei RNA sequencing on surgically resected human anterior and posterior hippocampus from epilepsy patients, identifying differentially expressed genes at cellular resolution. We further identify axis- and cell-type-specific gene expression signatures that differentially intersect with human genetic signals, identifying cell-type-specific genes in the posterior hippocampus for cognitive function and the anterior hippocampus for mood and affect. These data are accessible as a public resource through an interactive website.
