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
MYC proto-oncogene family including c-myc and n-myc (MYCN) are critical for normal cell development and tumorigenesis. Overexpression of c-myc causes acute erythroleukemia in vivo. However, the role of MYCN in acute erythroleukemia remains poorly understood. In this study, we found that the patients with erythroleukemia showed higher expression of MYCN than normal controls. In vitro experiments, knockdown of MYCN resulted in decreased cell proliferation, elevated autonomously cell apoptosis and increased P21-mediated cell senescence. On the contrary, overexpression of MYCN obviously promoted cell proliferation, and induced erythroid differentiation block and apoptosis resistance to cytotoxic agent. Further gene microarray and functional analysis revealed that EZH2 is a target of MYCN. Knockdown of MYCN inhibited the expression of EZH2, and then activated p21 expression through removal of H3K27me3 at the p21 promoter. Overexpression of ezh2 could antagonize the p21 activation caused by MYCN knockdown. In addition, Aurora inhibitor MLN8237 inhibited the proliferation of erythroleukemia cells through repression of MYCN/EZH2 axis, whereas it minimally affected the normal hematopoietic cells. In conclusion, MYCN contributes to the malignant characteristics of erythroleukemia through EZH2-meidated epigenetic repression of p21. MYCN may serve as a therapy target for the patients with acute erythroleukemia.
