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 the most common inheritable, solid neoplasm in children found under the age of 7 and accounts for approximately 7% of childhood cancers. A common treatment that has been prescribed for over a decade is retinoid therapy [using all‑trans retinoic acid (RA)]. Treatment with this differentiating agent has been revealed to progress the cells from their stem‑cell state to a mature neuronal state gaining classical neuronal characteristics, including the suppression of proliferation. However, the molecular mechanism underlying the action of RA treatment remains to be elucidated. In the present study, a novel mechanism of RA‑induced differentiation via regulation of receptor tyrosine kinase‑like orphan receptor 1 (ROR1) is reported. ROR1 is overexpressed in neuroblastoma but significantly downregulated in mature differentiated neurons. Hence, it was hypothesized that RA may modulate ROR1 leading to differentiation and termination of cancerous properties. Immunoblotting revealed that following RA treatment, ROR1 levels initially increased then sharply decreased by 96 h. This was paired with synaptophysin, a mature neuron marker, sharply increasing concurrently, providing evidence of differentiation by 96 h. Investigation of the ROR1 pathway confirmed ROR1‑dependent downstream activation of the PI3K/AKT signaling axis, a growth pathway previously demonstrated to promote differentiation. Chromatin immunoprecipitation revealed an increase in RAR binding to the promoters of ROR1 and its endogenous ligand, Wnt5a. This research provided compelling evidence that RA is able to modulate the expression of ROR1 and Wnt5a to promote differentiation through the expression of synaptophysin. This data combined with the overarching data from the scientific community regarding proliferation and other proliferative factors in early‑stage neurons provides a more in‑depth model of the process of differentiation in neurons.
