COPD Severity as an Independent Predictor of Long-Term Survival in Operable Lung Cancer: A Retrospective Analysis from a High-Volume Thoracic Surgery Center.

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
Purpose: This study aims to identify predictors of long-term survival in patients with chronic obstructive pulmonary disease (COPD) undergoing anatomical resections for non-small cell lung cancer (NSCLC), with focus on COPD severity, to improve perioperative risk stratification and patient care. Patients and Methods: This retrospective study included all patients with NSCLC and COPD undergoing anatomical resections at the Lung Tumor Center Munich between 2011 and 2020. COPD severity was classified by Global Initiative for Obstructive Lung Disease criteria: Group 1 (mild/moderate obstruction, COPD I-II) and Group 2 (severe obstruction, COPD III-IV). The relationship between COPD severity and perioperative parameters was analyzed using Kaplan-Meier and Cox proportional hazard model. Results: Of 1663 NSCLC patients undergoing anatomical resections, 476 (28.6%) patients with COPD I-IV (40.5% female, median age 67.28 [60.57; 73.27] years) were included. No significant differences were observed between groups in demographics, topography, TNM classification, histology of the primary tumor, and surgical approach. Group 2 experienced more frequently prolonged mechanical ventilation >2 days (p=0.016), air leaks >5 days (p = 0.020), and arrhythmias (p=0.012). Median overall survival (OS) was reduced in Group 2 (43.73 [30.14; 57.33] vs 85.30 [67.46; 103.14] months, p=0.001). Independent predictors of reduced OS included COPD III-IV (p<0.0001), pT Conclusion: COPD severity independently predicts perioperative morbidity and long-term survival in operable NSCLC patients. Comprehensive assessment of COPD severity can help in identifying high-risk patients and optimizing perioperative care.
