Sexual dimorphism in xenobiotic genetic variants-mediated risk for Parkinson's disease.
Article in Neurological sciences : official journal of the Italian Neurological Society and of the Italian Society of Clinical Neurophysiology, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
The vulnerability of dopaminergic neurons to environmental exposures in sporadic Parkinson's disease (PD) has been attributed to altered detoxification by xenobiotic metabolizing genes. Hence, we investigated the influence of genetic polymorphisms in xenobiotic metabolic pathway (CYP1A1 m1, CYP1A1 m2, CYP1A1 m4, COMT p.H108L, GSTT1, and GSTM1) on the susceptibility to PD. We used PCR-RFLP for CYP1A1 and COMT genotyping; multiplex-PCR for GSTT1 and GSTM1 deletion analysis; and spectrophotometric methods to evaluate the oxidative stress markers. Results showed association of CYP1A1 m1 (OR: 2.38, 95 % CI: 1.76-3.22) and COMT p.H108L (OR: 2.08 95 % CI: 1.56-2.77) polymorphisms with risk for PD. Male patients carrying combination of COMT p.H108L and CYP1A1 m1 variant alleles showed an early onset of the disease. There was a significant increase in oxidative stress makers such as malondialdehyde and protein carbonyls; and decrease in glutathione levels in PD cases compared to controls (P < 0.05). To conclude, CYP1A1 m1, COMT p.H108L polymorphisms were associated with PD risk, and sexual dimorphism was observed in these associations.
