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

objectiveTo explore the significance of assessing persistent airway obstruction (PAO) in asthma patients by airway wall remodeling with bronchoscopy, high-resolution computed tomography (HRCT), and biological markers in the induced sputum and serum, exhaled nitric oxide (FENO), and lung function.

methodsThe study was conducted in 119 patients with PAO and 125 patients with reversible airway obstruction (RAO). Endobronchial biopsy specimens were analyzed for airway smooth muscle (ASM) area, and reticular basement membrane (RBM) thickness. Airway thickness was also measured by HRCT scanning. Levels of matrix metalloproteases-9 (MMP-9), metalloproteinase 33 (ADAM33), and vascular endothelial growth factor (VEGF) were measured in the induced sputum and serum by enzyme linked immunosorbent assay.

resultPAO was associated with longer disease duration, absence of atopy and rhinitis, and larger ASM area (SMA%) (15.83%±2.32% [n=9] vs. 8.0%±1.68% [n=7], P=0.02), thicker RBM (16.27±2.32 μm [n=9] vs. 8.71±2.41 μm [n=7], P=0.042); No differences in any of the biomarker molecules measured in airway thickness in HRCT, sputum and blood individually between groups were found.

conclusionSevere asthma patients with longer disease duration and the absence of atopy and rhinitis are more likely to develop PAO in Chines Han population. PAO patients have increased ASM area and RBM thickness appear to be valuable in the evaluation of airway remodeling in asthma patients in Chinese Han population.
