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
Neuroblastoma is one of the most common cancers in infants and is often multidrug-resistant. One of the methods of treating neuroblastomas is to create conditions for their differentiation. In this work, we performed a full-transcriptome analysis of gene expression in an undifferentiated and differentiated in vitro human neuroblastoma cell line IMR-32 and identified the signaling pathways and biological processes that undergo the greatest changes during differentiation. The results obtained show that a complex heterogeneous population of nerve cells is formed at different stages of differentiation. In the cell population of differentiating neuroblastoma, the expression of genes in which cortical neuronal progenitor cells are enriched increases; at the same time, there are cells expressing markers of early postmitotic neurons. Cells differentiate in several different directions according to the type of synaptic mediator. At the same time, the differentiation of IMR-32 cells is accompanied by an increase in the transcription of genes that suppress the differentiation of nerve cells, Sox2 and PROM1, the expression of which is normally suppressed during in vivo differentiation.
