PON1 Q192R polymorphism (rs662) is associated with childhood embryonal tumors.
Article in Molecular biology reports, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers, 1 of them a synthesis that pooled 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.
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
Genetic susceptibility and environment exposures are associated risk factors in carcinogenesis. Gene polymorphisms that decrease the activity of detoxifying carcinogen substances may modify the effect of exposures. We investigated whether the polymorphisms PON1 rs662 (Q192R), and PON1 rs854560 (L55M) would be associated with embryonal tumors in Brazilian children. Blood samples from 163 children with embryonal tumors and 342 as control group were genotyped by TaqMAN real-time PCR assays. Logistic regression was used to evaluate the association between the polymorphisms of cases and controls groups, adjusted by skin color and age strata. When all tumors were taken together, the presence of the PON1 rs662 (Q192R) variant genotype (RR) was associated with an increased risk of developing embryonal tumors (OR = 2.80, 95 % CI 1.12-7.02). The presence of at least one variant PON1 rs662 R allele increased the risk of developing Wilms´ Tumor although without statistical power. However, it was observed a significant association of PON1 rs662 (Q192R) variant genotype (RR) with retinoblastoma (OR = 4.08, 95 % CI 1.13-14.97), whereas the PON1 rs854560 (L55M) polymorphism was not associated with any tumor. These results indicate that PON1 polymorphisms may have an influence on the risk of developing embryonal tumors.
