Spatial pattern enhanced cellular and tissue recognition for spatial transcriptomics.
Article in NAR genomics and bioinformatics, 2025. 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
Spatially mapping the cellular positions and their microenvironments with spatial transcriptomics (ST) shows great potential to illustrate key factors and mechanisms driving complex tissue organizations. The spatial data require specialized handling with different statistical and inferential considerations. Here, we develop SPECTRUM (Spatial Pattern Enhanced Cellular and Tissue Recognition Unified Method), which combines inclusive prior known cell-type-specific markers and spatial weighting for cell-type identification and spatial community detection. Comprehensive benchmarks demonstrate the superior performance of SPECTRUM. Applying SPECTRUM on real ST datasets with various spatial patterns demonstrates its capability in correctly mapping region-specific cell types and functional spatial communities. With that, we uncovered that context-dependent communication supports the functional plasticity of cells in spatial communities in human limb development. In summary, SPECTRUM is a unified tool for ST data analysis that deepens our insights into spatial organization at molecular, cellular, and community levels.
