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
LncRNAs have emerged as pivotal regulators in the development and progression of various human cancers. However, understanding the precise mechanisms by which lncRNAs influence cancer progression remains a substantial challenge, largely due to their cell type- and tissue-specific expression patterns and the lack of well-defined functional domains or motifs. In this study, we investigate the complex interplay between super-enhancers and lncRNAs through a comprehensive analysis of lncRNA expression in a cohort of metastatic castration-resistant prostate cancer patients. Our analysis identifies 1344 lncRNAs, among which an antisense lncRNA in the IGF1R locus named IGF1R-AS1 displayed the strongest super-enhancer association. Through pan-cancer transcriptome analysis, we find that IGF1R-AS1 is specifically transcribed in tumor specimens and is overexpressed in prostate and lung cancers. Notably, we reveal a non-canonical trans-acting role for IGF1R-AS1 whereby it interacts with chromatin remodeling complexes and architectural proteins to facilitate long-range chromatin looping between distal MYC enhancers and its promoter, leading to MYC overexpression and enhanced tumorigenicity. Collectively, our findings elucidate a mechanism by which a tumor-specific trans-acting lncRNA modulates oncogenic MYC expression through long-range chromatin interactions, suggesting IGF1R-AS1 may play an important role in the pathogenesis of MYC-driven malignancies.
