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
Dendritic cells (DCs) integrate innate immune sensing with adaptive immune priming through coordinated transcriptional programs that regulate antiviral defense, inflammatory signaling, and antigen presentation. However, the hierarchical organization and interdependence of these pathways following stimulation remain incompletely defined. Here, we performed an in silico re-analysis with full reproducibility of publicly available RNA-sequencing data (GSE108526) to characterize the temporal architecture and associations of immune transcriptional modules in human dendritic cells at 6 h and 16 h following innate immune activation. Principal component analysis revealed stimulation status as the dominant source of transcriptomic variance. Differential expression analysis confirmed robust induction of interferon-stimulated genes (ISGs) alongside modulation of inflammatory mediators and antigen presentation-associated genes. Module-level quantification showed that interferon signaling constituted the primary early transcriptional axis, whereas inflammatory cytokine programs displayed moderate induction and antigen presentation-associated genes exhibited distinct temporal dynamics. Association analysis demonstrated strong relationships between CIITA and downstream MHC class II genes, supporting coordinated antigen presentation regulation, while relationships between interferon and inflammatory modules were positive but non-proportional, indicating partial modular independence. Collectively, these findings reveal a structured yet non-uniform transcriptional organization in stimulated human dendritic cells, characterized by dominant interferon responses accompanied by context-dependent inflammatory activation and differentially associated antigen presentation programs. This integrative framework provides a reproducible systems-level approach for dissecting immune transcriptional architecture in human dendritic cell activation.
