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

Understanding how cellular architecture shapes cortical function requires mesoscopic approaches that resolve structure-function relationships in vivo. Here we introduce the cerebral blood flow (CBF) - cell-body staining intensity (CSI) similarity index (CCSI), a quantitative measure of laminar perfusion-cytoarchitecture coupling derived from whole-brain 1-mm isotropic 7 T arterial spin labeling and cell-body staining intensity profiles from the BigBrain atlas. Across 30 participants, CCSI revealed reproducible, region-specific alignment between laminar perfusion and cellular density distributions. CCSI was selectively associated with mitochondrial respiratory capacity per mitochondrion and colocalized with capillary endothelial and end-state oligodendrocyte populations. Gene ontology enrichment converged on metabolic regulation, neurovascular organization, and mitochondrial homeostasis. A parallel control analysis using quantitative T1 yielded no significant associations, supporting the specificity of these findings. At the systems level, CCSI improved structure-function gradient correspondence in higher-hierarchy association cortices. These results support CCSI as a reproducible, non-invasive mesoscopic index linking cortical perfusion, microstructure, and metabolism.
