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
objectiveTo explore the mechanism of tumor-associated fibroblasts (CAFs) for regulating proliferation and migration of prostate cancer (PCa) cells.
methodsWe conducted a bioinformatics analysis to identify miRNAs with high expression in PCa. The proliferation, migration and hsa-miR-18b-5p expression levels were observed in PCa cells co-cultured with CAFs. We further examined hsa-miR-18b-5p expression level in 20 pairs of PCa and adjacent tissue samples and in different PCa cell lines and normal epithelial cells using RT-qPCR. In PCa cell lines C4-2 and LNCAPNC, the effects of transfection with a hsa-miR-18b-5p inhibitor on cell proliferation, migration, invasion, drug resistance, apoptosis and cell cycle were evaluated, and the effects of has-miR-18b-5p knockdown on C4-2 cell xenograft growth and mouse survival were observed in nude mice. Dual luciferase reporter gene assay was used to validate the targeting relationship between hsa-miR-18b-5p and its target genes, whose expressions were detected in PCa cells using RT-qPCR and Western blotting.
resultsThe expression of hsa-miR-18b-5p was significantly increased in the co-culture of CAFs and PCa cell lines, which exhibited significantly enhanced proliferation and migration abilities. Transfection with has-miR-18b-5p inhibitor strongly attenuated the effect of CAFs for promoting proliferation and migration of PCa cells, and in C4-2 and LNCAP cells cultured alone, inhibition of hsa-miR-18b-5p obviously suppressed cell proliferation, migration, invasion, and drug resistance. In the tumor-bearing mice, hsa-miR-18b-5p knockdown in the transplanted cells significantly inhibited xenograft growth and increased the survival time of the mice. Target gene prediction suggested that FBXL3 was a potential target of hsa-miR-18b-5p, and dual luciferase reporter gene confirmed a binding site between them. In C4-2 and LNCAP cells, hsa-miR-18b-5p knockdown resulted in significantly increased expression levels of FBXL3.
conclusionCAFs promotes proliferation and migration of PCa cells by up-regulating hsa-miR-18b-5p to suppress FBXL3 expression.
