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
backgroundNon-small cell lung cancer (NSCLC) mainly includes lung squamous cell carcinoma and lung adenocarcinoma, and its extremely high morbidity and mortality are the main causes of poor prognosis in NSCLC patients. Therefore, it is particularly important to study the mechanisms associated with tumor proliferation and metastasis and explore new molecular targets of NSCLC. Studies have shown that Guanosine monophosphate synthase (GMPS) may serve as a potential drug target, but its biological function and molecular mechanism in NSCLC are still unknown. Therefore, it is urgently needed to investigate the molecular mechanisms of GMPS.
methodsWe first analyzed 30 cases of lung adenocarcinoma, lung squamous carcinoma and adjacent tissues; Then, lentiviral technology was used to construct overexpressed or knocked out cell lines to verify the function of GMPS. Then, RNA sequencing and Western blot experiments were carried out in animal experiments to explore the mechanism of GMPS. Our experimental results suggest that GMPS plays an important role in the progression of NSCLC.
resultsWe found that GMPS was highly expressed in lung adenocarcinoma and lung squamous cell carcinoma tissues, and was associated with poor prognosis of patients. Down-regulation of GMPS inhibits tumor progression. And GMPS promotes lung cancer cell migration through the SERPINB2-uPA axis, and DNMT1 is an intermediate factor in GMPS regulating SERPINB2 expression. Our experimental results show that GMPS expression is associated with lung cancer invasion and migration.
conclusionsOur findings revealed the correlation between GMPS and the prognosis of NSCLC at the tissue level. Secondly, GMPS can promote the progression of NSCLC. The molecular mechanism of GMPS affecting the metastasis of lung cancer cells was elucidated. These findings highlight the important role of GMPS in NSCLC, so as to provide new insights for the identification of new targets and lay a theoretical foundation for the clinical application of GMPS.
