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
backgroundA predominant Th17 population and impaired Treg function is the marker of nasal polyposis (NP) in Chinese patients. TGF-β1, a multifunction cytokine, is a vital factor involved in inducing or restricting specific Th cell development. However, its role in NP has still not been well understood.
methodsIn a double-blind trial, 30 subjects were randomized into 2 groups (15 steroid-treated NP, 15 untreated NP), and 15 normal subjects were allocated as control group. We analyzed the expression of TGF-β1, p-Smad2, p-STAT3, Smad7, SOCS3, IL-10, IL-17A, Foxp3, and RORc in the NP tissue of Chinese patients using mRNA and protein detection methods.
resultsTGF-β1, p-Smad2, IL-10, SOCS3, and Foxp3 expression was higher in steroid-treated NP patients than in untreated NP patients. Conversely, expression of p-STAT3, Smad7, IL-17A, and RORc was higher in untreated NP patients than in steroid-treated NP patients, demonstrating that TGF-β1 was more likely to contribute to Treg commitment in Chinese NP patients after intranasal steroid treatment.
conclusionsTGF-β1 may be a signature Treg cytokine, which is valuable for obtaining a clear understanding of the pathogenesis of NP. Moreover, intranasal steroid treatment attenuated the chronic inflammatory response in these patients by promoting Smad-dependent Treg functions and reducing STAT3-mediated Th17 reactions.
