1 · What the graph read from it

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.

2 · The registry

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

Alcohol dehydrogenase 4 (ADH4) is an important member of ADH family that metabolize a wide variety of substrates including ethanol and retinol. Studies demonstrated that ADH4 was involved in cancer. Microarray data showed that the expression of ADH4 was reduced in hepatocellular carcinoma (HCC). However, the role of ADH4 in HCC carcinogenesis remains undefined. The aim of this study is to explore the clinical significance of ADH4 in progression and prognosis of HCC. The expression levels of ADH4 in 15 paired HCC and noncancerous (NC) liver tissues were measured by qRT-PCR and those in 4 paired samples by Western blotting. Another 91 paraffin-embedded HCC tissues were examined by immunohistochemistry. The qRT-PCR result showed that the expression level of ADH4 mRNA in HCC was significantly lower than that in NC tissues (P<0.0001). Western blotting also displayed that ADH4 protein was notably reduced in HCC. Immunohistochemistry assay confirmed that ADH4 protein was remarkably reduced in 59.3% HCC. The expression of ADH4 was correlated with the pathology grade (P=0.031) and serum AFP (P=0.022). HCC patients with lower ADH4 expression had much worse overall survival rate than that with high expression (P<0.001). Furthermore, multivariate analysis showed that ADH4 expression was an independent predictor of overall survival (HR, 0.154; 95%CI, 0.044-0.543; P=0.004). This is the first time that the expression levels of ADH4 mRNA and protein have found to be markedly reduced in HCC tissues and significantly associated with survival, suggesting that ADH4 is a novel and potential prognostic marker for HCC patients.
