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
objectiveThe interaction between T cells, particularly naïve CD4 T cells (CD4Tn), and colorectal cancer (CRC) is highly complex. CD4Tn play a crucial role in modulating immune responses within the tumor microenvironment, yet the precise mechanisms by which they influence tumor progression remain elusive. This study aims to explore the relationship between CRC and CD4Tn, identify biomarkers and therapeutic targets, and focus on the role of CD4Tn in shaping the immune environment of CRC.
methodsSingle-cell transcriptomics, alongside the scPagwas algorithm, were employed to identify pivotal T cell subsets involved in CRC progression. Bulk transcriptomic data were further analyzed using deconvolution algorithms to elucidate the roles of these key T cell subsets. The abundance of naïve CD4 T cells (CD4Tn) was specifically assessed to gauge patient responses to immunotherapy, alterations in the immune microenvironment, and correlations with genetic mutations. Key genes linked to CD4Tn were identified using weighted gene co-expression network analysis and Pearson correlation scores. The SMR algorithm was subsequently used for validation, with experimental verification following.
resultsThrough single-cell transcriptomics and the scPagwas algorithm, CD4Tn was confirmed as a critical cell type in CRC progression. High infiltration of CD4Tn cells in CRC patients was correlated with poorer prognosis and suboptimal responses to immunotherapy. SMR analysis suggested a potential causal link between DRAM2 gene expression and CRC progression. Experimental knockdown of DRAM2 in colorectal cancer cells significantly inhibited tumor growth.
conclusionThe DRAM2 gene, associated with CD4Tn cells, appears to play a pivotal role in the advancement of CRC and may represent a promising therapeutic target for treatment.
