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
Background/Aim: Karyopherin alpha 2 (KPNA2) has been reported to be associated with cancer aggressiveness and treatment resistance via transporting several cargo proteins into the nucleus, such as cancer-promoting E2F and DNA repair-related MRN complex. Recent studies have highlighted the KPNA2 functions in tumorigenesis and the progression of various cancers. However, the importance of KPNA2 expression has yet to be elucidated in clinical neuroblastoma patients. This study aimed to analyze the clinical impact of KPNA2 expression in neuroblastoma. Materials and Methods: KPNA2 expression in 81 resected neuroblastoma sections was examined using immuno-histochemical staining. The significance and prognostic value of tumoral KPNA2 expression were analyzed using our cohort and R2 database. Results: The KPNA2 was expressed in the nucleus of neuroblastoma cells. The expression level of nuclear KPNA2 was not associated with clinicopathological factors in neuroblastoma. Among our cohort (n=81), non-radically resected neuroblastoma patients (n=37) with high KPNA2 expression had poorer prognoses than those with low KPNA2 expression. The R2 database analysis validated that the high KPNA2 expression was related to the poor prognosis in the large-scale neuroblastoma cohort. Conclusion: KPNA2 expression evaluation in neuroblastoma is a promising indicator of prognosis in non-curative resected cases. KPNA2 targeting may be a promising therapeutic strategy against advanced neuroblastoma.
