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
Objectives: The goal of the study was to examine the relationships among micrometastasis, pathological degree of differentiation and survival in patients with esophageal squamous cell carcinoma (SCC). Design: A single-center retrospective study of patients diagnosed with thoracic esophageal SCC. Methods: Immunostaining using CK13 was carried out for all lymph nodes resected by radical esophagectomy with three-field lymphadenectomy. The relationships among micrometastasis to lymph nodes, degree of differentiation and survival were investigated. Results: The 25 patients included 14 (56.0%) well-differentiated and 11 (44.0%) moderately differentiated cases. In multivariate analysis, well-differentiated cases were not related to micrometastasis (odds ratio (OR): 1.5, confidence interval (CI): 0.2-12, p=0.7). In multivariate analysis of survival, cases in pStage III or higher were likely to have shorter survival (hazard ratio (HR): 2.8, CI: 0.7-12, p=0.16), and those with micrometastasis also tended to have shorter survival (HR: 2.7, CI: 0.8-9, p=0.11)); however, well-differentiated cases were not significantly related to survival (HR: 1.5, CI: 0.4-5.5, p=0.5). Conclusion: Micrometastasis to lymph nodes may be a prognostic factor even in advanced esophageal cancer. The degree of differentiation was not related to micrometastasis or survival.
