Comparison of mycology between different types of chronic rhinosinusitis.
Article in Journal of the Chinese Medical Association : JCMA, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundThe aim of this study was to culture fungi from the nasal discharge of patients with chronic rhinosinusitis (CRS) using both a traditional and Ponikau et al's method, and subsequently compare the culture results between CRS with nasal polyps (CRSwNPs) and without nasal polyps (CRSsNPs), and between eosinophilic and noneosinophilic CRS.
methodsEighty-one CRS patients with CRS who underwent functional endoscopic sinus surgery were enrolled. Before surgery, the severity of each patient's CRS was evaluated through an endoscopic examination and CT scan. Swab samples were collected from the middle meatus for traditional fungal cultures using cotton-tipped sticks. Afterward, the ipsilateral nasal cavity was irrigated, with the irrigated fluid processed using Ponikau et al's method for fungal culture.
resultsThe endoscopic and CT scores were significantly higher in CRSwNPs than CRSsNPs, but were not different between eosinophilic CRS and noneosinophilic CRS. Using Ponikau et al's method, 61/81 (75.3%) of the specimens grew fungi. Among them, 20 of 32 (62.5%) CRSwNPs specimens and 41 of 49 (83.7%) CRSsNPs specimens grew fungi. For eosinophilic CRS specimens, 35 of 46 (76.1%) grew fungi, and 26 of 35 (74.3%) noneosinophilic CRS specimens grew fungi. The fungal culture rate was borderline significantly higher in CRSsNPs than CRSwNPs ( p = 0.058) but was not significantly different between eosinophilic CRS and noneosinophilic CRS ( p = 1). However, Cladosporium was significantly more common in CRSsNPs than CRSwNPs ( p = 0.048).
conclusionOur results showed that the mycology of CRS was different between CRSwNPs and CRSsNPs.
