Association of High-Sensitivity C-Reactive Protein Levels with Proximal Airway CT Morphology in Obesity.
Article in Obesity surgery, 2025. 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
objectiveObesity and airway collapse are closely associated, yet the underlying mechanisms remain unclear. This study aimed to evaluate airway collapsibility in relation to markers of adiposity and high-sensitivity C-reactive protein (hs-CRP) levels in obese individuals.
methodsWe conducted a cross-sectional study comparing changes in the lumen area and circularity of proximal airways using chest CT imaging in four groups: obese individuals (BMI 30-39.9 kg/m
resultsMorbidly obese individuals with high hs-CRP exhibited the most pronounced airway collapse, with regional asymmetry in collapsibility. hs-CRP was significantly associated with BMI, android and gynoid fat mass, and subcutaneous adipose tissue area (all P < 0.001). In multivariate analysis, change in airway circularity was associated with BMI and change in airway lumen area was associated with BMI and hs-CRP, but neither was related to adiposity distribution.
conclusionThe inflammatory aspects of obesity, reflected by hs-CRP, may exacerbate proximal airway collapse and regional ventilation abnormalities beyond the mechanical effects of fat accumulation.
