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
In patients with acute promyelocytic leukemia (APL), ~98% express the promyelocytic leukemia (PML)‑retinoic acid receptor α (RARα) fusion protein. Previous studies have shown that, in primary leukemia cells of patients with APL, the cleavage of PML‑RARα by neutrophil elastase is important for its ability to initiate APL. This cleavage separates the nuclear localization signal (NLS) from PML, leading to the formation of a novel protein, NLS‑RARα, although its underlying mechanism in APL remains to be fully elucidated. In the present study, the role of NLS‑RARα on the proliferation and differentiation of APL NB4 cells was investigated. Lentiviral vectors were constructed and transfected NLS‑RARα in NB4 cells, puromycin was used to select the stable transfected cell lines. Cell Counting Kit‑8 and flow cytometry analysis revealed that the efficient overexpression of NLS‑RARα significantly promoted NB4 cell proliferation and inhibited all‑trans retinoic acid‑induced cell differentiation. Furthermore, the NLS‑RARα protein promoted a significant increase in AKT and glycogen synthase kinase 3β (GSK‑3β) phosphorylation. The protein levels of phosphorylated (p) AKT and pGSK‑3β were decreased following pretreatment with the phosphatidylinositol 3‑kinase (PI3K) inhibitor, LY294002. These findings suggested that NLS‑RARα was an important molecule associated with the occurrence of APL via the PI3K‑AKT signaling pathway, and indicated that the NLS‑RARα protein may be a novel target for the treatment of APL.
