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
Hypoxia is a typical hallmark of solid tumors and plays a crucial role in the progression of esophageal squamous cell carcinogenesis (ESCC). Nevertheless, the precise mechanisms underlying the involvement of hypoxia in tumor development remain unclear. In the present study, a novel hypoxia-induced long noncoding RNA (lncRNA) is identified first, lnc191, which is highly expressed in clinical ESCC tissues and is positively correlated with poor prognosis of ESCC patients. These findings provide evidence that the hypoxia-inducible factor-1α (HIF-1α)-mediated transcriptional activation of lnc191 enhances the growth and metastasis of ESCC cells both in vitro and in vivo. Mechanistically, lnc191 interacts with GRP78 (78-kDa glucose-regulated protein), one of the endoplasmic reticulum chaperone proteins, leading to its translocation to the membrane, where GRP78 binds with EGFR and enhances its phosphorylation (Y845), further activates ERK/MAPK signaling pathway, and thereby in favor of the progression of ESCC. Overall, this data proposes lnc191 as a key driver during the development of ESCC and reveals the participation of the activated GRP78/ERK/MAPK axis in the ESCC progression mediated by lnc191. These findings indicate the potential of lnc191 as a promising diagnostic biomarker and therapeutic target in ESCC.
