[Chronic rhinosinusitis was neither a risk nor a protective factor during the COVID-19 pandemic].
Article in HNO, 2025. 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
backgroundThere are various views in the literature regarding the influence of chronic rhinosinusitis (CRS) as a comorbidity on the occurrence of COVID-19 disease.
objectiveDid CRS prevent or promote infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) during the coronavirus pandemic? MATERIALS AND
methodsWe conducted a retrospective case-control study with 252 adult CRS patients who underwent sinus surgery between 2020 and 2023 and a non-CRS control group; both groups were comparable in terms of age and gender. The association between a history of COVID‑19 and CRS according to its phenotype and endotype was examined using cross tables and chi-square tests. We also analyzed self-reported and measured olfactory ability. Additionally, patients were asked about continuous preoperative use of inhaled corticosteroids.
resultsThere was no association between CRS and COVID‑19. This applied both to CRS patients with or without nasal polyps (CRSwNP or CRSsNP) and to endotyping according to tissue eosinophilia. The majority of operated CRS patients were CRSwNP patients, predominantly male and younger compared to CRSsNP patients. CRSwNP presented eosinophilia 2.8 times more frequently than CRSsNP. CRSsNP patients had better reported and measured olfactory ability compared to CRSwNP patients. The measured olfactory ability of the CRS patients with COVID‑19 did not differ from that of CRS patients without C‑19. Preoperative use of inhaled corticosteroids was more frequent among CRSwNP patients than CRSsNP patients.
conclusionChronic rhinosinusitis was neither a risk nor a protective factor for COVID‑19.
