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.
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
objectiveGenetic susceptibility to lung cancer is the subject of extensive research. We investigated whether polymorphisms in the microsomal epoxide hydrolase (EPHX1) gene is linked to lung cancer susceptibility in Jordanian patients.
methodsIn this case-control study a total of 218 subjects from Jordan University Hospital and King Hussein Cancer Center were screened (108 lung cancer patients and 110 matched controls). Polymerase chain reaction-restriction fragment-length polymorphism (PCR-RFLP) was used to detect the two common polymorphisms in EPXH1 located in exons 3 and 4; namely, amino acid substitution from tyrosine to histidine at residue 113 of exon 3 (Tyr113His; low activity allele) and amino acid substitution from histidine to arginine at residue 139 of exon 4 (His139Arg; high activity allele).
resultsThere was no significant difference in genotype distribution between control subjects and lung cancer patients. In addition, no differences were found when evaluated according to age, gender or tobacco consumption. For exon 3 the adjusted OR was 0.970 (95% CI 0.473 - 1.991) for the Tyr113/His113 genotype and 0.692 (95% CI 0.301 - 1.590) for the Tyr113/Tyr113 genotype, respectively. For exon 4 the adjusted OR was 0.596 (95% CI 0.297-1.197) for the His139/Arg139 genotype and 0.882 (95% CI 0.117- 6.660) for the Arg139/Arg139 genotype, respectively. Logistic regression analysis did not show differences in EPXH1 distributions between patients and controls when categorized according to predicted microsomal epoxide hydrolase activity. Therefore, common polymorphisms within EPHX1 do not appear to be significant risk factors for lung cancer development in the Jordanian population.
conclusionNo associations were observed between lung cancer risk and EPXH1 polymorphisms in the Jordanian population.
