Incidence and Risk Factors for Postoperative Delirium Following Robotic and Video-Assisted Pulmonary Lobectomy: Analysis of the Nationwide Inpatient Sample, 2005-2020.
Article in Clinical epidemiology, 2026. 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
Background: Postoperative delirium (POD) is a critical yet underrecognized complication following pulmonary lobectomy, particularly in older adults. While robotic-assisted thoracoscopic surgery (RATS) and video-assisted thoracoscopic surgery (VATS) offer advantages over open thoracotomy, their impact on POD is uncertain. This study aimed to determine the incidence and risk factors of POD following RATS or VATS pulmonary lobectomies. Methods: This retrospective study analyzed data from patients aged ≥50 years who underwent RATS or VATS lobectomies for lung cancer using the Nationwide Inpatient Sample (2005-2020). POD was identified using International Classification of Diseases (ICD) codes. Logistic regression was used to assess associations between patient demographics, comorbidities, perioperative complications, and POD risk. Results: Among 35,853 patients (mean age: 68.8 years; 55.9% female), 1.7% developed POD. POD risk was similar between patients receiving RATS and VATS. Key risk factors for POD included advanced age (RATS: adjusted odds ratio [aOR]=1.05, 95% confidence interval [CI]: 1.04-1.07; VATS: aOR=1.08, 95% CI: 1.06-1.09), pneumonia (RATS: aOR=2.23, 95% CI: 1.36-3.66; VATS: aOR=2.77, 95% CI: 1.98-3.86), and infection. Other factors associated with POD were persistent anemia, moderate/severe renal disease, and mechanical ventilation. Conclusion: POD risk was similar between RATS and VATS pulmonary lobectomies and was associated with several patient-related and perioperative factors. These findings may help inform perioperative risk assessment and postoperative monitoring in older adults undergoing minimally invasive pulmonary lobectomy.
