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 evaluate the association between CYP1A1 and GSTs genetic polymorphisms and susceptibility to esophageal squamous cell carcinoma (SCC) and esophageal adenocarcinoma (ADC) in a high risk area of northwest of France.

methodsA case-control study was conducted to investigate the genetic polymorphisms of these enzymes (CYP1A1*2C and GSTP1 exon 7 Val alleles, GSTM1*2/*2 and GSTT1*2/*2 null genotypes). A total of 79 esophageal cancer cases and 130 controls were recruited.

resultsGSTM1*2/*2 and CYP1A1*1A/*2C genotype frequencies were higher among squamous cell carcinomas at a level close to statistical significance (OR = 1.83, 95% CI 0.88-3.83, P = 0.11; OR = 3.03, 95% CI 0.93-9.90, P = 0.07, respectively). For GSTP1 polymorphism, no difference was found between controls and cases, whatever their histological status. Lower frequency of GSTT1 deletion was observed in ADC group compared to controls with a statistically significant difference (OR = 13.31, 95% CI 1.66-106.92, P<0.01).

conclusionIn SCC, our results are consistent with the strong association of this kind of tumour with tobacco exposure. In ADC, our results suggest 3 distinct hypotheses: (1) activation of exogenous procarcinogens, such as small halogenated compounds by GSTT1; (2) contribution of GSTT1 to the inflammatory response of esophageal mucosa, which is known to be a strong risk factor for ADC, possibly through leukotriene synthesis; (3) higher sensitivity to the inflammatory process associated with intracellular depletion of glutathione.
