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

aimTo investigate the effect of Helicobacter pylori (H pylori) infection on the expressions of Bcl-2 family members in gastric adenocarcinoma.

methodsGastric adenocarcinoma and resection margin tissues of 95 patients were studied. Semi-quantitative RT-PCR was used to measure Bid, Bax and Bcl-2 mRNA expressions.

resultsExpressions of Bid and Bax in gastric adenocarcinoma tissues without H pylori infection, with cagA- H pylori infection and cagA+ H pylori infection increased significantly in turn (Bid, 0.304, 0.422 and 0.855 respectively, P<0.05; Bax, 0.309, 0.650 and 0.979 respectively, P<0.05). Bcl-2 mRNA levels increased significantly in gastric adenocarcinoma tissues with cagA- H pylori infection and cagA+ H pylori infection, compared with those without H pylori infection (0.696 and 0.849 vs 0.411, P<0.05). Expressions of Bid, Bax and Bcl-2 in resection margin tissues without H pylori infection, with cagA- H pylori infection and cagA+ H pylori infection increased significantly in turn (Bid, 0.377, 0.686 and 0.939 respectively, P<0.05; Bax, 0.353, 0.645 and 1.001 respectively, P<0.05; Bcl-2, 0.371, 0.487 and 0.619 respectively, P<0.05). In H pylori negative specimens, expressions of Bid and Bax correlated negatively with that of Bcl-2 respectively in adenocarcinoma tissues (Bid vs Bcl-2, r=-0.409, P<0.05; Bax vs Bcl-2, r=-0.451, P<0.05). In H pylori positive specimens, expressions of Bid and Bax did not correlate with that of Bcl-2 in adenocarcinoma tissues (Bid vs Bcl-2, r=0.187, P>0.05; Bax vs Bcl-2, r=0.201, P>0.05), but correlated positively with that of Bcl-2 respectively in resection margin tissues (Bid vs Bcl-2, r=0.331, P<0.05; Bax vs Bcl-2, r=0.295, P<0.05).

conclusionH pylori may enhance Bid, Bax and Bcl-2 mRNA levels and cause deregulation of these apoptosis-associated genes expressions, which may play a role during development of gastric adenocarcinoma induced by H pylori.
