Clinical Characteristics and Influencing Factors of Postoperative Pain in Patients Undergoing Gastric Endoscopic Submucosal Dissection.

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: To comprehensively analyze the clinical characteristics of patients who underwent gastric endoscopic submucosal dissection (ESD) and explore the incidence and influencing factors of postoperative pain. Methods: The clinical data of patients who underwent gastric ESD at our center from 2009 to 2024 were retrospectively analyzed. Pain severity was assessed using a visual analogue scale, with a score ≥ 4 defined as postoperative pain. Based on the presence or absence of postoperative pain, patients were divided into a pain group and a control group. Independent factors influencing postoperative pain were identified using multivariate logistic regression analysis. To control for confounding bias, patients in the case and control groups were matched by sex and lesion size, and the matched participants were further analyzed using a conditional logistic regression model. Results: In total, 993 patients were analyzed. The incidence of postoperative pain was 9.1% (95% confidence interval [CI], 7.3-11.1). In the univariate analysis, sex, operation duration, anesthesia method, intraoperative electrocoagulation, nasogastric tube placement, and postoperative vomiting were significantly associated with postoperative pain. Multivariate analysis identified eight independent factors: male sex (odds ratio [OR], 0.61; 95% CI, 0.37-0.97; Conclusion: Female sex, diabetes mellitus, concave-type lesions, lesions in the gastric antrum, non-intubation general anesthesia, absence of intraoperative electrocoagulation, prolonged operation duration, nasogastric tube placement, and postoperative vomiting were independent factors associated with moderate to severe pain after gastric ESD. For patients at increased risk of postoperative pain, appropriate prophylactic and therapeutic measures during the perioperative period may effectively alleviate pain following gastric ESD.
