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

backgroundAs monoclonal antibodies have proven effective in managing recalcitrant chronic rhinosinusitis with nasal polyps (CRSwNP), the concept of disease remission is evolving, underscoring the need for a comprehensive, multimodal evaluation of disease burden over time.

objectiveThis study first presents ultrastructural changes of the nasal epithelium in patients treated with dupilumab, assessing the potential for mucosal regeneration during long-term follow-up.

methodsTen patients (n = 10) were enrolled. Baseline (T0) outcomes included Nasal Polyp Score, Lund-Kennedy Score, 22-item Sinonasal Outcome Test, Visual Analog Scale for nasal symptoms, and CT-scan Lund-Mackay Score. Mucosal samples were collected from the posteromedial aspect of prior antrostomies and analyzed using both light microscopy and transmission electron microscopy (TEM). Outcomes and mucosal sampling were reassessed at 12-month (T1) and compared. Logistic bivariate analysis was performed to assess the relationship between ultrastructural tissue characteristics and clinical outcomes.

resultsSignificant improvements in all outcomes were observed at T1. A ciliated columnar epithelium was identifiable in most patients (n = 7/10). Intercellular junctions, including desmosomes, tight and adherens junctions, were evident in half of the sample (n = 5/10). Three patients (n = 3/10) showed no evidence of epithelial regrowth. Endoscopic and radiologic outcomes were significantly linked to ultrastructural findings at T1. Higher eosinophilic infiltration at T0 was a positive predictor for the presence of pseudostratified epithelium at T1.

conclusionsThese first preliminary data suggest that ultrastructural response is achievable in most patients with CRSwNP. Larger cohorts are required to strengthen these findings and support the concept of disease remission in course of mAb.
