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

objectiveThis study was performed to investigate the correlation between P15 methylation and hepatocellular carcinoma (HCC) and hepatocirrhosis using a meta-analysis of available case control studies.

methodsPrevious studies have primarily evaluated the incidence of P15 methylation in HCC and corresponding control groups, and compared the incidence of P15 methylation in liver cirrhosis and control groups. Data regarding publication information, study characteristics, and incidence of P15 methylation in both groups were collected from these studies and summarized.

resultsTen studies that assessed P15 gene methylation in 824 HCC tumour tissues and five studies analyzing P15 methylation in 155 liver cirrhosis tissues met our inclusion criteria. Our meta-analysis revealed that the rate of P15 methylation was significantly higher in HCCs than in adjacent non-tumour tissues (OR 9.04, 95% CI 5.80-14.09, P < 0.00001). Moreover, P15 methylation was significantly higher in liver cirrhosis tissues than in control tissues (OR 7.82, 95% CI 3.58-17.07, P < 0.00001).

conclusionswe found that P15 methylation was associated with an increased risk of HCC and liver cirrhosis. P15 hypermethylation induced the inactivation of the P15 gene, which played an important role in hepatocarcinogenesis.
