Preventing sino-nasal polyposis recurrence after functional endoscopic sinus surgery: a multicentric study.
Article in American journal of clinical and experimental immunology, 2026. 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
backgroundChronic rhinosinusitis with nasal polyps (CRSwNP) frequently recurs after functional endoscopic sinus surgery (FESS), particularly in patients with eosinophilic inflammation or aspirin-exacerbated respiratory disease (AERD). Optimizing postoperative medical regimens based on disease severity may reduce recurrence rates. The aim of this study was to evaluate the impact of severity-based postoperative medical regimens on recurrence rates following FESS in patients with CRSwNP.
methodsThis prospective multicentric cohort study included 144 patients with CRSwNP who underwent FESS between 2021 and 2023. Patients were stratified into five groups based on eosinophilia, AERD status, and radiologic/endoscopic severity using the Modified Lund-Mackay (MLM) and Modified Lund-Kennedy (MLK) scores. Each group received a tailored postoperative medical regimen. Patients were followed for two years, with recurrence assessed via nasal endoscopy and scored using MLK.
resultsThe overall recurrence rate at two years was 10.4%. Recurrence rates increased progressively from 0% in Group 1 (non-eosinophilic) to 33.3% in Group 5 (AERD). The trend was statistically significant (Cochran-Armitage test, Z = 3.48, P < 0.001). A significant association between follow-up group and recurrence was found (Chi-square, P = 0.006, Cramér's V = 0.316). Blood eosinophilia and elevated IgE levels were strongly correlated (P < 0.001, OR = 3.15).
conclusionPostoperative recurrence in CRSwNP can be significantly reduced by tailoring medical regimens based on clinical, radiologic, and immunologic severity. Group-based stratification provides a feasible model for personalizing care, especially in settings where biologics are unavailable.
