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

aimsMechanisms of Epstein-Barr virus (EBV) associated gastric tumour development are incompletely understood. The interrelations between EBV infection, apoptosis, cell proliferation, and the expression of the tumour suppressor gene p53 was investigated in 133 early stage gastric carcinomas.

methodsTumour tissue was compared with paired non-tumour tissue. EBV encoded small RNAs (EBERs) determined EBV status. The apoptotic index (AI) was determined by morphology and verified biochemically. p53 and Ki-67 expression (cell proliferation) was assessed using immunohistochemistry.

resultsEBV was detected in 14.3% of the cases. Cell proliferation did not differ significantly between EBV positive and negative cancers. However, within both these groups, the p53 positive and negative subsets differed significantly (EBV positive group: 76.8% and 55.3% were p53 positive or negative cancers, respectively; p<0.05; EBV negative group: 65.2% and 51.7% were p53 positive or negative, respectively; p<0.005). The numbers of p53 expressing EBV positive and negative cases were significantly different (57.9% and 82.5%, respectively; p<0.05). Compared with cell proliferation, apoptosis was significantly lower in EBV positive versus negative cancers (AI of 4.36 and 6.50, respectively; p<0.01). The p53 positive and negative subsets also differed significantly in AI (EBV positive group: AI of 5.13 and 3.30 for p53 positive and negative cancers, respectively; p<0.05: EBV negative group: AI of 6.84 and 4.90 for p53 positive and negative cancers, respectively; p<0.05).

conclusionsThese factors probably combine to promote development and progression of early stage gastric carcinomas and, at the same time, ensure the survival of EBV itself.
