Switching biologics in chronic rhinosinusitis with nasal polyps: A multicenter Canadian experience.
Article in International forum of allergy & rhinology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 15 papers, 1 of them a synthesis that pooled 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.
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
backgroundType 2 biologics have been used increasingly for the treatment of chronic rhinosinusitis with nasal polyps (CRSwNP). However, patterns of biologic switching are understudied, and established guidelines for sequential or simultaneous use do not yet exist.
methodsThis is a Canadian multicenter retrospective study of real-world patient data. Patients were included if they had recurrent CRSwNP despite maximal medical and surgical management, and received at least one dose of a type 2 biologic. Patients who remained on their initial biologic comprised the continuous group. Patients with sequential or simultaneous use of more than one biologic comprised the switched group. We compared the characteristics of patients who continued and switched biologics.
resultsNote that 225 consecutive patients were included. Thirty-six (16%) switched biologics at least once, and six (3%) switched twice. The most common switch was from mepolizumab to dupilumab, with poor control of CRSwNP symptoms being the leading cause for this switch. Lack of efficacy was the main reason for switching off mepolizumab and omalizumab, while adverse events were the leading cause for switching off dupilumab. Additionally, mepolizumab patients were more likely to switch biologics late in their treatment, while dupilumab patients rarely switched after 12 months of therapy (p-value < 0.001).
conclusionsSwitching biologics for CRSwNP is frequent in Canadian rhinology practices, with 16% of patients switching at least once. The most common switch is from mepolizumab to dupilumab with inadequate CRSwNP control driving this switch. This study may help guide sequential or simultaneous use of biologics in CRSwNP patients.
