Diabetes mellitus is associated with short-term postoperative outcomes in patients undergoing vats lobectomy for lung cancer: a 7-year retrospective analysis.

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: Diabetes mellitus (DM) is a prevalent metabolic disorder and a well-recognized perioperative risk factor across non-cardiac surgical populations. However, its correlative association with short-term postoperative complications after video-assisted thoracoscopic surgery (VATS) lobectomy remains insufficiently characterized. This study explores the relationship between DM and postoperative outcomes using a large national inpatient database. Methods: A retrospective cohort study was conducted based on the 2016-2022 Nationwide Inpatient Sample. Adult patients undergoing VATS lobectomy for lung cancer were identified via International Classification of Diseases, 10th Revision coding, and participants were stratified by the presence or absence of DM. Multivariable logistic regression were used to evaluate the correlative links between DM and postoperative complications after adjusting for demographic, comorbid, and hospital-related covariates. Results: A total of 34,398 eligible patients were included in the final cohort, among whom 7,515 (21.84%) had a diagnosis of DM. Diabetic patients were older and had a higher overall comorbidity burden compared with non-diabetic counterparts, accompanied by a higher crude incidence of in-hospital postoperative complications. After multivariable adjustment, DM was associated with elevated odds of acute respiratory insufficiency [odds ratio (OR) 1.177; 95% confidence interval (CI): 1.077 to 1.286; P<0.001], myocardial infarction (OR 1.714; 95% CI: 1.561 to 1.882; P<0.001), delirium (OR 1.509; 95% CI: 1.198 to 1.902; P<0.001), requirement for mechanical ventilation (OR 1.208; 95% CI: 1.033 to 1.412; P=0.02), and supraventricular arrhythmia (OR 1.143; 95% CI: 1.073 to 1.218; P<0.001). An inverse correlation between DM and acute pneumothorax was also observed (OR 0.869; 95% CI: 0.778 to 0.971; P=0.01). Conclusions: This large nationwide observational cohort reveals correlative associations between DM and increased risks of cardiopulmonary and neurological complications following VATS lobectomy for lung cancer. These observational findings provide supportive insights for perioperative risk assessment and optimized metabolic management in diabetic patients undergoing minimally invasive thoracic surgery.
