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
backgroundColorectal cancer (CRC) represents a growing global health burden, particularly in developing countries. Mesenchymal stem cells (MSCs) have been reported to suppress tumor progression partly through the release of exosomes that deliver therapeutic molecules. However, the therapeutic potential of engineered MSC-derived exosomal microRNAs (Exo-miRNAs) in CRC remains largely unexplored.
methodsPlasma exosome miRNA sequencing was performed to identify dysregulated miRNAs in CRC. Gain- and loss-of-function assays were conducted to evaluate the biological effects of candidate miRNAs in CRC cells. Human mesenchymal stem cells (hMSCs) were engineered to overexpress miR-3614-5p via Lipofectamine-mediated transfection, and exosomes enriched with miR-3614-5p were isolated and characterized. The effects of engineered hMSC-derived exosomal miR-3614-5p (Exo-miR-3614-5p) on CRC progression were assessed both in vitro and in vivo. Mechanistic studies were performed to identify downstream targets and signaling pathways.
resultsmiR-3614-5p was identified as a therapeutic miRNA that was significantly downregulated in CRC. Engineered hMSCs efficiently loaded miR-3614-5p into secreted exosomes. Treatment with Exo-miR-3614-5p markedly suppressed CRC cell proliferation in vitro and inhibited tumor growth in vivo. Mechanistically, miR-3614-5p directly bound to the 3' untranslated region (3'UTR) of IL7Rα, resulting in translational repression and subsequent inactivation of the JAK2/STAT3 signaling pathway. In addition, miR-3614-5p exhibited potential diagnostic value for CRC.
conclusionsThis study demonstrates that engineered hMSC-derived exosomal miR-3614-5p effectively inhibits CRC progression primarily through downregulation of IL7Rα and suppression of the JAK2/STAT3 signaling pathway. These findings suggest that Exo-miR-3614-5p represents a promising therapeutic and diagnostic candidate for CRC.
