Peri-Operative Surgical Risk and Postoperative Outcomes in Patients With COPD Undergoing Abdominal Surgery: A Retrospective Observational Study.
Article in Cureus, 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 Chronic obstructive pulmonary disease (COPD) is a major global health burden and a leading cause of death and disability, commonly encountered in surgical populations where it independently predicts adverse outcomes. Increased postoperative mortality and morbidity arise from pathophysiological changes such as lung hyperinflation, intrinsic positive end-expiratory pressure (PEEP), impaired gas exchange, and reduced lung volumes after major abdominal surgery. The interaction between disease severity, surgical factors, and anesthesia duration underscores the need for structured peri- and postoperative risk assessment to reduce complications in this vulnerable group. Methods This retrospective observational study, conducted over 23 months at Faridpur Medical College Hospital, reviewed the records of 107 consecutive patients aged 40 years and old with spirometrically confirmed COPD who underwent elective abdominal surgery under general anesthesia. Strict inclusion and exclusion criteria were applied to ensure diagnostic accuracy and minimize bias, focusing on patients with post-bronchodilator first second of forced expiration (FEV
