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: Gastric intraepithelial neoplasia (GIN) is a key precancerous lesion of gastric cancer, and discrepancies between preoperative endoscopic forceps biopsy (EFB) pathology and postoperative pathology after endoscopic submucosal dissection (ESD) pose significant challenges for accurate diagnosis and treatment planning. Objective: To analyze the risk factors for pathological upgrade in patients with GIN after an ESD procedure. Design: Retrospective study. Methods: A retrospective analysis was conducted on 682 patients diagnosed with GIN by gastric EFB pathology at the Digestive Endoscopy Center of Wuxi People's Hospital from January 2018 to December 2024 (490 with low-grade intraepithelial neoplasia (LGIN) and 192 with high-grade intraepithelial neoplasia (HGIN)). Demographic characteristics (gender, age, BMI, chronic disease history, fecal occult blood), endoscopic features of lesions (location, morphology, size), and pathology data after the ESD procedure were collected. Univariate, multivariate, and stepwise logistic regression analyses were performed to identify independent risk factors for pathological upgradation. Results: The total pathological upgrade rate after ESD was 59.4% (51.2% in the LGIN group and 80.2% in the HGIN group). Stepwise regression analysis revealed that a maximum lesion diameter ⩾2 cm (odds ratio (OR) = 2.49) was the most significant risk factor for pathological upgrade. Meanwhile, age ⩾70 years, comorbid hypertension, Paris classification type IIc lesion, and a lesion location at the gastric angle or cardia were independent risk factors for pathological upgrade, whereas a type IIb lesion demonstrated a protective effect (OR = 0.61). Conclusion: Advanced age (⩾70 years), hypertension, lesion size ⩾2 cm, type IIc morphology, and lesions in the gastric angle/cardia significantly increase the risk of pathological upgrade after ESD. These findings provide a basis for preoperative risk assessment and individualized treatment strategies for GIN patients.
