Impact of COPD pulmonary structural remodeling on the prognosis of patients with advanced lung squamous cell carcinoma.

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
Background: By observing the changes of lung imaging airway structure in patients with advanced lung squamous cell carcinoma（ALUSC）, the relationship between the different types of COPD pulmonary structural remodeling and the prognosis of patients with ALUSC was analyzed. Methods: We reviewed the medical records of 278 patients with ALUSC. The degree of emphysema and the percentage of bronchial wall thickness（WT%） on chest HRCT were calculated by Synapse3D software, Lung structural remodeling can be divided into there types: airway remodeling dominated, emphysema dominated, and mixed types. Results: Compared with the diagnosis, the Goddard score increased, the proportion of airway remodeling dominated type decreased and the proportion of mixed type increased during the progression of ALUSC. In Kaplan-Meier analysis, whether with or without COPD, the mPFS and mOS of patients with mixed type were the shortest, and the difference was statistically significant. Univariate and multivariate Cox proportional hazard regression analysis showed that mixed type was an independent risk factor for poor PFS and OS in patients with ALUSC. Conclusion: Patients with ALUSC all have varying degrees of lung structural remodeling, and patients with mixed lung structural remodeling have the worst prognosis. In addition, the aggravation of emphysema during tumor progression is more pronounced than the thickening of the airway wall, and the changes of emphysema was more powerful in predicting the progression of ALUSC.Clinicians must pay more attention to the changes of COPD (especially emphysema) in the process of diagnosis and treatment of ALUSC.
