1 · What the graph read from it

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.

2 · The registry

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

backgroundIn current clinical practice, primary diffuse chronic rhinosinusitis with nasal polyps (CRSwNP) is classified into two endotypes: type 2 and non-type 2. Previous studies on sinonasal health-related quality of life (HRQoL) in CRS have primarily focused on differences between phenotypes. This study aimed to compare HRQoL between the two endotypes in patients with CRSwNP. The type 2 endotype had a higher median nasal polyp score (NPS) than non-types (4 and 2, respectively), but this difference did not reach significance. Loss of smell was associated with NPS, and facial pain/pressure was inversely correlated with age. Age was significantly associated with loss of smell, but only in non-type 2 CRSwNP.

methodsThis was a prospective, monocentric study conducted between 2018 and 2023 on CRSwNP patients referred for surgery. Health-related quality of life was assessed using the German standardized SNOT-20 questionnaire. Type 2 was defined according to the updated EPOS/EUFOREA 2023 criteria.

resultsA total of 122 patients with CRSwNP were included, 113 (92.6%) of whom were classified as type 2. Type 2 was associated with a significantly worse SNOT-20 German Adapted Version score. Two of the four cardinal symptoms of CRS-loss of smell and rhinorrhea-were significantly more severe and prevalent in the type 2 endotype, with loss of smell being very specific. The most prevalent symptom in both endotypes was nasal obstruction, with no difference between both endotypes. The type 2 endotype had a higher median nasal polyp score (NPS) than non-types (4 and 2, respectively), but this difference did not reach significance. Loss of smell was associated with NPS, and facial pain/pressure was inversely correlated with age. Age was significantly associated with loss of smell, but only in non-type 2 CRSwNP.

conclusionType 2 CRSwNP has a more severe impact on HRQoL compared with non-type 2 CRSwNP. Hyposmia, rhinorrhea, and potentially NPS may offer endotypic and pathophysiological insights.
