Dosing Interval Extension of Dupilumab in CRSwNP: Five-Year Real World Outcomes.
Article in International forum of allergy & rhinology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 4 papers.
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
backgroundChronic rhinosinusitis with nasal polyps (CRSwNP) is a persistent, often Type 2-mediated inflammatory disease that markedly impairs quality of life. While dupilumab provides rapid improvement, there is limited evidence on long-term outcomes beyond 2 years, and the clinical impact of dosing-interval extension remains unclear. We therefore set out to evaluate long-term real-world outcomes of dupilumab therapy in CRSwNP and assess the effectiveness and safety of dosing-interval extension after achieving disease control.
methodsThis retrospective single-center cohort included 224 adults with CRSwNP (37% with nonsteroidal anti-inflammatory drug-exacerbated respiratory disease) treated with dupilumab for up to 4.5 years with outcomes modeled to 5 years. Longitudinal changes in polyp size, symptom burden, olfaction, asthma control, and Type 2 biomarkers were analyzed using mixed-effects models. Outcomes were then compared between patients who maintained standard 2-week dosing and those who voluntarily extended dosing intervals after achieving stable control.
resultsDupilumab led to significant improvements in polyp burden, olfactory function, and quality of life peaking within 6 months, with sustained benefit through 5 years according to longitudinal modeling. Forty percent of patients extended dosing intervals without loss of efficacy and reported fewer treatment-related adverse events. Overall, 16% experienced side effects, most commonly musculoskeletal complaints, followed by skin reactions and injection site reactions.
conclusionLong-term dupilumab therapy provided durable disease control and excellent safety. Personalized dosing-interval extension maintained efficacy and reduced treatment burden, supporting its potential role in optimizing long-term management of CRSwNP, especially in patients with troublesome side effects.
