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

backgroundCytochrome P4501B1 (CYP1B1) a phase I enzyme, is involved in the activation of a broad spectrum of procarcinogens. Impacts on the catalytic activity of the CYP1B1 enzyme, as well as an association of the Leu432Val polymorphism with the risk of lung cancer, have been described; however, the results remain controversial.

methodsWe conducted a meta-analysis of all available studies to clarify the effects of the Leu432Val polymorphism on lung cancer risks basing on 2,543 lung cancer cases and 3,304 controls from ten separate comparisons. We also performed subgroup analyses by ethnicity (categorized as Caucasian, Asian and African-American), gender, smoking status ,and histological type. A pooled odds ratio (OR) with 95% confidence interval (CI) was calculated to estimate the strength of the association.

resultsA significantly increased risk was found in our meta-analysis in the overall population (Val/Val vs. Leu/Leu: OR = 1.371, 95% CI 1.137-1.652, P = 0.001). In subgroup analysis, significant associations with lung cancer susceptibility were also found in Caucasians (Val/Val vs. Leu/Leu: OR = 1.312, 95% CI 1.075-1.602, P = 0.008), females (Val/Val vs. Leu/Leu: OR = 1.472, 95% CI 1.097-1.976, P = 0.010), and smokers (dominant model Leu/Val + Val/Val vs. Leu/Leu: OR = 1.257, 95% CI 1.016-1.554, P = 0.035). Null results were noted in the subgroup analysis by histological type under different genetic models.

conclusionsOur results suggest that the CYP1B1 Leu432Val polymorphism acts as a risk factor for the carcinogenesis of lung cancer.
