Shikonin-mediated up-regulation of miR-34a and miR-202 inhibits retinoblastoma proliferation.
Article in Toxicology research, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It has been retracted, and should not be counted. Cited by 10 papers.
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
Retinoblastoma (RB) is an ocular tumor that occurs mainly in children. The pathogenesis of RB is not well understood, and its treatment strategies are very limited. Shikonin is widely reported as an anti-tumor agent. However, its effect on RB is still unknown. MTT assay was performed to detect the proliferation ability of two RB cell lines, Y-79 and WERI-Rb-1, upon treatment with Shikonin. Colony formation assay was conducted to examine the clonogenic ability of Shikonin-treated cells. Real-time PCR and western blotting were performed for expression analysis of miRNAs and MYCN, respectively. Luciferase activity assay was conducted to test the inhibition mechanism of miR-34a and miR-202 on MYCN. Shikonin could effectively inhibit the proliferation of RB cells and upregulate the expressions of miR-34a and miR-202. MiR-34a and miR-202 could directly target the mRNA degradation of oncogene MYCN, and the inhibitory effect of Shikonin was largely weakened by restoring the MYCN protein expression. Shikonin-mediated up-regulation of miR-34a and miR-202 inhibits RB proliferation, partially mediated through MYCN.
