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 pathogenesis of persistent allergic rhinitis with chronic and refractory nasal obstruction is still unknown. Inflammation and tissue remodeling are known to play a role, but this has not been studied thoroughly. The purpose of this study is to identify the profile of gene expression of inflammatory and remodeling markers in nasal mucosa of patients with PAR and chronic obstruction.
methodsAfter informed consent, we obtained nasal mucosa tissue from five aeroallergen-sensitized PAR patients undergoing anterior turbinectomy, and control non-sensitized individuals undergoing cerebrospinal fluid fistula repair or rhinoplasty. We assessed the expression of 34 genes related to inflammation and tissue remodeling using the real-time polymerase chain reaction (qPCR) to quantify each mRNA.
resultsIL-4 mRNA was upregulated in nasal mucosa of all five patients; CCR3, CCR8 and Eotaxin-2 were upregulated in four out of five patient samples; while IL-5 and IL-13 were upregulated in two of them. TGF-β1 was not upregulated in PAR samples. mRNA from metalloproteinases MMP-7, MMP13 and MMP15 were upregulated in three out of five samples. Our results indicate a typical mRNA expression profile of the infiltrating inflammatory Th2 cells and eosinophils, combined with altered gene expression of remodeling-related proteins in stromal cells from the mucosa.
conclusionProlonged allergen challenge can lead to persistent upregulation of genes for inflammatory mediators such as IL-4 Th2/eosinophil cytokines, chemokines and receptors, which may play an important role in maintaining PAR with chronic nasal obstruction. Our findings may have therapeutic implications, including the use of anti-IL4, -CCR3 or -MMP therapy to ameliorate the condition.
