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
Ischemia-reperfusion injury (IRI) is one of the leading causes of mortality and disability worldwide. Owing to its complex pathogenesis, there is still a lack of effective therapeutic targets in clinical practice, and exploring the mechanism and targets of IRI is still a major clinical challenge. This study aimed to explore the genetic alterations in leukocytes in peripheral blood after ischemia-reperfusion, aiming to discover new biomarkers and potential therapeutic targets. KAS-Seq (Kethoxal-assisted single-strand DNA sequencing) was used to obtain gene expression profiles of circulating leukocytes in a porcine ischemia-reperfusion model at 24, 48, and 72 h post-ischemia‒reperfusion. This method integrated genes that exhibited regular changes over time. In this study, we thoroughly analyzed the dynamic changes in gene expression post-IRI, revealing significant enrichment in key signaling pathways that regulate immune responses and T-cell activation over time. Our identification of the interleukin-7 receptor (IL7R) was particularly striking, as it plays a crucial molecular role in IRI. Additionally, using database mining technology, we confirmed the close relationship between IL7R and IRI, explored the interaction between interferon-γ (IFNG) and IL7R in T-cell activation, and clarified their joint influence on ischemia-reperfusion injury. Using KAS-Seq analysis of leukocytes from peripheral blood, we successfully delineated the temporal patterns of gene expression and changes in signal transduction pathways in porcine models of ischemia-reperfusion. Subsequent in-depth analysis identified IL7R as a potential novel therapeutic target for IRI. The pivotal role of this gene in modulating immune responses provides innovative avenues for the development of IRI treatments.
