Glutathione-S-Transferase Deletions and Non-arteritic Anterior Ischemic Optic Neuropathy.
Article in Molecular neurobiology, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
In this study, we aimed at investigating the association between glutathione-S-transferase (GSTM1 and GSTT1) deletion genotypes and susceptibility to non-arteritic anterior ischemic optic neuropathy (NAION). We hope our findings may contribute to the understanding NAION pathogenesis and provide some clues for the prevention and treatment of optic diseases. The NAION group contains 113 subjects (33 males and 80 females, mean age 55.3 ± 9.8). And 98 subjects were enrolled in the control group (32 males and 66 females, mean age 56.7 ± 10.2). The individuals involved in the study were matched by gender and age to obtain two homogenous groups. GSTM1- and GSTT1- genotype and the combined genotype were investigated. The genotype distributions in NAION patients were compared with those in the controls. Significantly altered intraocular pressure (IOP) and cup-to-disc ratio (CDR) was detected between NAION patients and controls. An increased risk of NAION was observed among individuals with GSTM1- (P < 0.001). No significant difference was confirmed for GSTT1- (P = 0.290). Individuals with GSTM1-/GSTT1- have a higher susceptibility to NAION (P < 0.001); the GSTM1-/GSTT1+ genotype also had a significantly higher frequency in patients than in controls (P = 0.004). But the genotype of GSTM1+/GSTT1- seems to have no connection with NAION (P = 0.476). In conclusion, in this study, we confirmed the connection between NAION and GSTM1- genotype. But no significant association was observed between GSTT1- genotype and NAION susceptibility. In further analysis regarding combined genotype, a trend of protective effect was detected for GSTT1+ genotype. It is indicated by our result that oxidative compounds might play an important part in the pathogenesis of NAION.
