Glutathione S-transferase M1 and T1 gene polymorphisms in Brazilian women with endometriosis.
Article in Journal of assisted reproduction and genetics, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
purposeThe glutathione family (GST) genes appear to play a role in the genesis of endometriosis. This case-control study aimed to compare the frequencies of GSTM1 and GSTT1 polymorphisms in women with endometriosis and women without endometriosis.
methodsPolymerase chain reaction was performed to analyze the GSTM1 and GSTT1 genotypes among women with surgically and histologically confirmed endometriosis (case group n = 121) and in women without evidence of endometriosis confirmed by laparoscopy for investigation the infertility or for laparoscopic tubal sterilization (control group n = 97). RESULT(S): No differences in the frequencies of GSTM1 polymorphism (null genotype) were observed between the cases and controls: odds ratio (OR) = 1.13; 95 % CI 0.656-1.93 (p = 0.659). The GSTT1 polymorphism (null genotype) was more prevalent in the endometriosis group than in the control group (OR = 0.53; 95 % CI 0.94-0.29 (p = 0.039). No relationship between menstrual cycle interval and GSTM1 null genotype frequency was observed in either cases or controls (p = 0.370 and p = 0.664, respectively). In addition, no relationship between menstrual cycle interval and GSTT1 null genotype was observed in cases (p = 0.797) or controls (p = 0.052).
conclusionsGSTM1 null genotype frequency was similar between cases and controls. The GSTT1 null genotype was more frequent in the control group.
