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: Patients with gastric cancer (GC) are prone to lymph node metastasis (LNM), which is an important factor for recurrence and poor prognosis of GC. Nowadays, more and more studies have confirmed that exosomes can participate in tumor lymphangiogenesis. An in-depth exploration of the pathological mechanism in the process of LNM in GC may provide effective targets and improve the diagnosis and treatment effect. Materials and Methods: We used sequencing analysis of collected serum to screen out exo-miRNA related to LNM in GC. ELISA, qRT-PCR, Western Blot, RNA pull-down assay, Transwell assay, animal experiments, and other experiments were used to verify the results. Results: In this study, we screened out miR-224-3p related to GC progression and LNM in a vascular endothelial growth Factor C (VEGFC)-independent manner. We found that exo-miR-224-3p derived from GC cells could enter human lymphatic endothelial cells (HLECs) and promote the tube formation and migration of HLECs. In addition, it was revealed that miR-224-3p could bind to the 3'UTR region of GSK3B mRNA. Then, we proved that inhibiting the expression of GSK3B could suppress the phosphorylation of β-catenin and promote the transcription of PROX1, thus leading to tumor lymphangiogenesis. Furthermore, it was also found that hnRNPA1 mediated the sorting of miR-224-3p into exosomes, and the high expression of PKM2 promoted the secretion of exo-miR-224-3p. Conclusions: Our discovery of the exo-miR-224-3p/GSK3B/β-catenin/PROX1 axis may provide a new direction for the clinical treatment of GC.
