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
objectiveEndoscopic submucosal dissection (ESD) has become a first-line treatment for early esophageal cancer and precancerous lesions; however, non-curative resection (N-CR) occurs in a significant proportion of cases, necessitating additional surgical or chemoradiotherapy treatment. This study aimed to analyze the risk factors associated with N-CR following ESD and compare the efficacy of different secondary treatment strategies.
methodsWe conducted a retrospective analysis of 306 patients who underwent ESD for early esophageal lesions at The Fourth Hospital of Hebei Medical University between January 2017 and December 2021. Patients were divided into curative resection (CR) and non-curative resection (N-CR) groups. Univariate and multivariate logistic regression analyses were performed to identify independent risk factors for N-CR. A predictive nomogram model was constructed using R software. For the 49 patients with N-CR, we compared recurrence rates at 3 months, 1 year, and 2 years among three treatment strategies: no additional treatment (n = 22), surgical resection (n = 17), and chemoradiotherapy (n = 10).
resultsThe overall N-CR rate was 16.0% (49/306). Multivariate analysis identified four independent risk factors for N-CR: gastroscopic pathology (OR = 0.186, 95% CI: 0.037-0.948, P = 0.043), depth of infiltration (OR = 0.012, 95% CI: 0.002-0.077, P < 0.001), lesion location (OR = 0.185, 95% CI: 0.038-0.890, P = 0.035), and gross morphological type (OR = 0.018, 95% CI: 0.002-0.209, P = 0.001). The nomogram demonstrated good predictive accuracy. The 2-year recurrence rates were 18.18% for the no-treatment group, 11.79% for the surgical group, and 10.00% for the chemoradiotherapy group. No significant differences in overall survival or disease-free survival were observed among the three groups (P > 0.05).
conclusionsESD is a safe and effective treatment for early esophageal lesions. Gastroscopic pathology, depth of infiltration, lesion location, and gross type are independent predictors of N-CR. The predictive nomogram can assist clinical decision-making. Both surgical resection and chemoradiotherapy provide effective secondary treatment options for N-CR cases, with comparable oncological outcomes.
