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
Pancreatic cancer (PC) is mainly derived from the exocrine pancreatic ductal epithelial cells, and it is strongly aggressive malignant tumor. Due to its insidious onset and the lack of effective diagnostic biomarkers, PC currently remains one of the main causes of cancer-related mortality worldwide. Recent studies have found that hsa_circ_0001846 is involved in the progression of multiple cancers and has the potential to become biomarkers, but its function and mechanism in PC remains unclear. We found by qRT-PCR experiments that hsa_circ_0001846 was upregulated in PC cells and tissues, while circBase, Sanger sequencing, agarose gel electrophoresis and FISH experiments identified the splicing site, ring structure and cellular localization of hsa_circ_0001846. Various functional experiments by using the construction of small interfering RNA targeting hsa_circ_0001846 and overexpression plasmid demonstrated that hsa_circ_0001846 promoted the proliferation, migration and invasion of PC cells. Moreover, the tumor weight and volume of nude mice were significantly reduced after the stable knockdown of hsa_circ_0001846. In the mechanism exploration, RNA pull-down experiments and dual-luciferase experiments helped us to determine that hsa_circ_0001846 regulated the KRAS expression by sponging miR-204-3p in PC, thus playing a pro-cancer role. In this study, the effect of miR-204-3p on PC was also explored for the first time, and we found that knockdown of miR-204-3p reversed the tumor suppressive effect caused by silencing hsa_circ_0001846, and silencing KRAS also rescued the pro-cancer effect caused by overexpression of hsa_circ_0001846. In conclusion, our study revealed the pro-cancer role of hsa_circ_0001846 in PC, and for the first time identified the mechanism that hsa_circ_0001846 regulated KRAS by sponging miR-204-3p to promote PC progression and had the potential to become a cancer biomarker.
