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

backgroundAsthma is a heterogeneous disease with various inflammatory subtypes, including the type-2 (T2) endotype associated with airway eosinophilia. Severe asthma is linked to reduced ventilatory function due to airway structural changes. This study compared the extent of airway remodeling in different immunological endotypes of asthma.

methodsSevere asthma patients (n = 30) were stratified based on bronchial expression of T2 (e.g., CST1) and T3 (e.g., IL17A) immunity genes as T2-high, T3-high, or low-inflammatory. We analyzed airway wall thickness using endobronchial ultrasound (EBUS), bronchial biopsy morphometry, and mRNA expression of remodeling genes. Bronchial epithelial cell cultures were used to assess cytokine responses.

resultsT2-high asthma patients showed lower predicted FEV1 (59 vs. 74 % in low-inflammatory variant, p = 0.049) and increased submucosa layer (L2) in EBUS (0.203 vs. 0.189 mm, p = 0.018). T2-high asthma patients also had increased airway smooth muscle (ASM) mass (∼2-fold, p = 0.018) and marginally thicker reticular basement membrane. T3-high asthma showed only a trend toward thicker L2 (p = 0.055). Only patients with an eosinophilic signature in endobronchial biopsy demonstrated increased expression of remodeling genes, including TGFB1. A profibrotic profile was also induced in bronchial epithelium stimulated in vitro with IL-13.

conclusionThese data suggest that T2-signature in severe asthma is associated with increased ASM mass and more pronounced airway obstruction. Overexpression of remodeling genes primarily occurred in patients with signs of eosinophilic infiltration in the bronchial mucosa, suggesting that remodeling may progress with uncontrolled airway inflammation.
