Interpretable AI model reveals spatial codes of cell recruitment in tissues.
Article in Nature biomedical engineering, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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 which molecular signals recruit specific cells to precise tissue locations is fundamental to tissue biology, immunity and disease. Existing computational tools for spatially resolved transcriptomics (SRT) describe where cells reside but cannot explain why. Here we introduce SPACER, a fully interpretable multi-instance learning framework that decodes gene-level recruitment rules directly from SRT data. Applied to 37 SRT datasets spanning multiple human tumour types and mouse heart, SPACER achieved 4-21-fold improvement over existing methods in various tasks of recovering biologically meaningful recruitment signals. SPACER revealed (1) that tumour-expressed mucins are associated with physical barriers to T cell engagement, which predicts resistance to immune checkpoint inhibitors and patient prognosis, (2) that local antigen presentation is the dominant correlate of T cell engagement across cancer types and (3) that Cd4
