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
Alzheimer's disease (AD) is a complex neurodegenerative disorder and the most common type of dementia in the elderly. Although its cause is not completely known, several studies suggest that oxidative stress plays an important role in the etiology of this disease. The SIRT1 and SOD2 proteins are linked to pathways that may impair oxidative stress. In this study, we analyzed the association between polymorphisms in these genes and in the APOE gene, through RT-PCR, as well as between environmental factors and the risk of AD. Additionally, the thiobarbituric acid reactive substance assay was performed to estimate the plasma level of malondialdehyde (MDA), a biomarker of lipid peroxidation. Furthermore, some cytogenetic studies indicate that cells of AD patients show increased chromosomal damage; thus, we performed the micronucleus cytome assay to assess cytogenetic damage in AD patients. As expected, the APOE polymorphisms were found to be highly associated with AD. Additionally, the CT genotype of the SIRT1 gene showed a positive association with the disease. The frequencies of genomic damage (micronucleus, buds, nucleoplasmic bridges and binucleated cells), the presence of cell death biomarkers (condensed chromatin, karyorrhexis and pyknosis), and the plasma level of MDA were significantly greater in AD patients than in controls. Our results support the hypothesis that AD is a condition with increased oxidative stress and genomic instability, which may contribute to the neurodegeneration in AD.
