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 clarify the association between CYP2E1 PstI/RsaI polymorphism and susceptibility to colorectal cancer.

methodsA meta-analysis based on 10 eligible case-control studies involving 4979 cases and 6012 controls was carried out to summarize the data on the association between CYP2E1 RsaI/PstI polymorphism and colorectal cancer risk.

resultsIn comparison of the homozygote c2c2 and c2 carriers (c1c2 + c2c2) and the homozygous wild-type genotype (c1c1), no association was found between CYP2E1 RsaI/PstI polymorphism and colorectal cancer risk [odds ratio (OR) = 1.24 (95% CI: 0.93-1.66) for c2c2; OR = 1.02 (95% CI: 0.88-1.19) for c2 carriers]. In stratified analysis, Caucasians with c2c2 homozygote appeared to have an increased risk of colorectal cancer (OR = 2.67, 95% CI: 1.03-6.89, P = 0.043), no significant associations were found in other groups.

conclusionc2c2 homozygote of CYP2E1 PstI/RsaI polymorphism may be associated with the increased risk of colorectal cancer in Caucasians, which needs further investigations.
