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 salient feature of the tumor microenvironment. HIF-1α is a master regulator of hypoxic adaption. The polycomb repressor complex 2 (PRC2) molecule Ezh2 is known to play roles in essential cellular processes of cell fate decisions. However, how PRC2-mediated epigenetic dynamic changes take part in hypoxic adaption is not completely understood. Recently, we identified a long non-coding RNA (lncRNA) named HITT (HIF-1α inhibitor at translation levels) that plays roles in modulating hypoxia-mediated angiogenesis and tumor growth in vivo. In this study, we reveal an important activity of HITT in evading hypoxia-induced apoptosis by coordinating with PRC2 activity to regulate HIF-1α transcription. Genetic or chemical inhibition of PRC2 significantly elevates HIF-1α mRNA levels. The occupancy of Ezh2 and its substrate H3K27me3 on the HIF-1α promoter is detected under normoxia, and is reduced by hypoxia. Restoring hypoxia-inhibited HITT expression rescues the association between Ezh2/H3K27me3 and the HIF-1α promoter, which also simultaneously abrogates hypoxia-induced HIF-1α mRNA transcription. Further mechanistic studies revealed that HITT inhibits HIF-1α transcription by guiding Ezh2 through the formation of an RNA-DNA triplex with the HIF-1α promoter. Importantly, HITT/Ezh2-regulated HIF-1α transcription leads to alerted HIF-1α protein output and elicits a significant effect to evade hypoxia-induced apoptosis. Importantly, a close association between HIF-1α mRNA and HITT was further verified in human colon cancer tissues in vivo. Collectively, these findings suggest a model for the epigenetic regulation of hypoxia-induced HIF-1α transcription modulated by lncRNA HITT, which provides important insights into how tumor cells sense and adapt to hypoxic stress.
