Differential Expression of Antioxidant and Oxidant Pathways in Chronic Rhinosinusitis Without Nasal Polyps.

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
Chronic rhinosinusitis without nasal polyps (CRSsNP) is a chronic inflammatory disease that lacks a clear pathogenesis/pathophysiology. While large studies focused on elucidating the pathophysiology of CRS with NPs (CRSwNP), this study aimed to use a systemic evaluation approach to identify the redox gene expression profile, its association with oxidative damage in CRSsNP, and the differences between CRSsNP and -wNP. The expression of 84 redox genes was analyzed using real-time PCR array in control and CRSsNP nasal mucosae. Changes in the mRNA and protein levels of these redox differentially expressed genes (DEGs) were verified using a customized real-time PCR array, RT-PCR, and Western blotting in an additional 18 patients. 4-Hydroxynonenal (lipid peroxidation) and 3-nitrotyrosine (protein nitrosylation) expression, representing oxidative stress (OxS) and nitrosative stress (NsS) status, were examined using immunohistochemistry. We found 27 DEGs (24 upregulated and 3 downregulated) in CRSsNP. AKR1C2, GCLM, GPX2, NOS2, and NQO1 were upregulated and LPO was downregulated more than 4-fold. These changes led to a substantial increase in OxS in CRSsNP nasal mucosa. In a comparison of the currently identified 27 DEGs with the 23 previously reported CRSwNP genes, there were 16 unique redox DEGs expressed between CRSsNP and -wNP. A String protein interaction network analysis revealed that CRSsNP possessed "an adaptive antioxidant defense signature", while CRSwNP showed "a pro-inflammatory and -oxidant pathway". Collectively, we systemically performed transcriptomic analysis to profile OxS-related genes in CRSsNP and highlighted the unique redox gene sets and pathway differences between CRSsNP and -wNP.
