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
backgroundAntioxidants may reduce risk of aggressive prostate cancer, and single-nucleotide polymorphisms (SNP) in antioxidant genes may modify this association.
methodsWe used Cox proportional hazards regression to examine circulating prediagnostic α-tocopherol, γ-tocopherol, and lycopene; SNPs in SOD2 (n = 5), CAT (n = 6), GPX1 (n = 2), GPX4, (n = 3); and their interactions and risk of lethal prostate cancer among 2,439 men with nonmetastatic prostate cancer in the Health Professionals Follow-up Study and Physicians' Health Study.
resultsWe observed 223 events over a median follow-up of 10 years. Higher α-tocopherol levels were associated with lower risk of lethal prostate cancer [HR 3rd versus 1st quartile (Q): 0.51; 95% confidence interval (CI), 0.30-0.89; HR 4th versus 1st Q: 0.68; 95% CI, 0.41-1.13; P trend: 0.02]. Men homozygous for the less common allele (G) at rs3746165 in GPX4 had a 35% lower risk of lethal prostate cancer compared with men homozygous for the more common allele (A; HR, 0.65; 95% CI, 0.43-0.99). Among men homozygous for the less common allele in rs3746165, high γ-tocopherol levels were associated with a 3.5-fold increased risk of lethal prostate cancer (95% CI, 1.27-9.72; P value, 0.02; interaction P value, 0.01).
conclusionsAmong men with nonmetastatic prostate cancer, higher circulating prediagnostic α-tocopherol may be associated with lower risk of developing lethal disease. Variants in GPX4 may be associated with risk of lethal prostate cancer, and may modify the relation between γ-tocopherol and prostate cancer survival. IMPACT: Circulating tocopherol levels and variants in GPX4 may affect prostate cancer progression. Cancer Epidemiol Biomarkers Prev; 23(6); 1037-46. ©2014 AACR.
