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
Background: Lung metastasis has garnered significant attention due to its prevalent occurrence. Pre-metastatic niche (PMN) establishment is a critical prerequisite for the onset of lung metastasis. Emerging evidence indicates that long noncoding RNAs (lncRNAs) play pivotal roles in the metastatic cascade to the lungs. However, the relationship between lncRNA expression profiles and the formation of PMN remains uncharacterized. This study aims to explore the expression profiles and potential roles of lncRNAs in the context of pre-metastatic lung microenvironment. Methods: RNA sequencing was utilized to elucidate the lncRNA landscape in pre-metastatic lung of murine models. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses were performed to infer the prospective functions of the differentially expressed lncRNAs. Among these, lncRNA Gm5144-202 in alveolar macrophages (AMs) was further scrutinized for its role in driving M2 macrophage polarization, facilitating the formation of PMN, and orchestrating the apoptosis, proliferation, and migration of tumor cells Results: A total of 232 lncRNAs exhibited differential expression in pre-metastatic murine lungs compared to normal controls, predominantly enriching pathways such as PI3K-Akt signaling, calcium signaling, neuroactive ligand-receptor interaction, and NF-κB signaling. Notably, lncRNA Gm5144-202 exhibited the most pronounced difference, with elevated level in alveolar macrophages (AMs) during the pre-metastatic phase. Silencing of lncRNA Gm5144-202 impeded the polarization of M2-like macrophages, suppressed the expression of factors critical for the formation of the PMN, and inhibited tumor cell invasion. Conclusions: Our research delineated the lncRNA expression profiles in pre-metastatic pulmonary tissues and identified, for the first time, the pivotal role of lncRNA Gm5144-202 in modulating M2 macrophage polarization and tumor cell invasiveness. Consequently, targeting lncRNA Gm5144-202 holds substantial promise for translational applications aimed at mitigating pulmonary metastasis.
