DDX21 Is a Potential Biomarker for Predicting Recurrence and Prognosis in Hepatocellular Carcinoma.

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
DEAD-box helicase 21 (DDX21) is a conserved Asp-Glu-Ala-Asp (DEAD) box RNA helicase with multiple functions that is involved in various cellular processes and diseases. However, the role of DDX21 in the recurrence and prognosis of hepatocellular carcinoma (HCC) patients remains unknown. In the current study, we examined the protein expression of DDX21 in HCC tissues through immunohistochemical staining and analyzed the correlation between DDX21 protein expression and clinical outcome via Kaplan-Meier survival analysis. The Cox proportional hazards regression model was used to assess the interrelationships between the outcome and variable over time. Our results showed that increased expression of DDX21 protein was observed in HCC tissues compared with paracancerous tissues and was associated with advanced BCLC stage. Recurrent HCC patients had higher levels of DDX21 protein than nonrecurrent cases. Notably, DDX21 was an independent risk factor for predicting worse overall survival and recurrence-free survival in HCC patients. Furthermore, lack of DDX21 abated the growth and mobility of Hep3B cells. Taken together, our data highlight the clinical significance of DDX21 in the recurrence and prognosis of HCC patients and indicate that targeting DDX21 may represent an effective therapeutic strategy for the treatment of HCC.
