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

Advanced spatially resolved transcriptomic (SRT) technologies preserve the spatial context of gene expression within tissues, enabling the study of context-dependent transcriptional regulation. Here, we propose a variational inference-assisted sparse Gaussian-process (VISGP) framework for identifying spatially variable genes (SVGs) and inferring spatially dependent cellular interactions from SRT data. VISGP combines sparse Gaussian-process approximations with variational inference via inducing variables to reduce computational and memory costs while enabling gene-specific adaptation of spatial covariance structures. Across simulated data and four real SRT datasets, VISGP detected more SVGs than existing methods and identified 85 spatially constrained ligand-receptor pairs that were missed by alternative approaches. Together, VISGP provides a scalable and statistically grounded strategy for decoding spatial gene regulation and cell-cell communication, yielding biological insights into cellular heterogeneity and cancer pathology.
