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
Colchicine is a widely prescribed anti-inflammatory drug for the treatment of gout, familial Mediterranean fever and pericarditis, but its narrow therapeutic window presents a significant risk of severe toxicity. Despite its clinical relevance, the molecular mechanisms underlying colchicine's pharmacological effects and associated toxicity and explored potential therapeutic interventions to mitigate its adverse effects. We showed the colchicine's impact on cellular morphology in human umbilical vein endothelial cells (HUVEC) and HeLa cells including cell rounding and detachment following 24 h of exposure that revealed pronounced cytotoxic effects. We then established a large-scale screening model to identify small molecules capable of reversing colchicine-induced cellular toxicity, and identified MLN4924, an inhibitor of the Cullin-RING E3 ligase (CRL) system, as a promising candidate for mitigating colchicine-induced cellular injury. Through a comprehensive multi-omics approach including transcriptomics, proteomics, phosphoproteomics and ubiquitinomics, we systematically characterized the molecular perturbations caused by colchicine and delineated the protective mechanisms of MLN4924. We found that MLN4924 exerted its protective effects by modulating critical cellular pathways, specifically preventing the dysregulation of cell cycle progression, mitotic disruption and microtubule destabilization triggered by colchicine. Furthermore, proteomic and phosphoproteomic analyses revealed significant alterations in kinase signaling networks, with combined inhibition of CDK1 and PAK1 emerging as an effective strategy to counteract colchicine-induced cellular dysfunction. These results not only provide a detailed molecular characterization of colchicine toxicity but also identify key therapeutic targets, laying the groundwork for the development of targeted interventions to mitigate colchicine-induced adverse effects in clinical practice.
