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: Lymph nodal characteristics are highly significant in predicting the survival of patients with esophageal squamous cell carcinoma (ESCC). However, there is currently a scarcity of studies examining their role in locally advanced ESCC. In the present study, we attempted to depict the patterns of regional lymph node metastasis and investigate their predictive potential in locally advanced ESCC. Methods: Patients with locally advanced ESCC underwent esophagectomy at the Department of Thoracic Surgery, The First Affiliated Hospital of Shantou University Medical College were included. Kaplan-Meier curve was used to compare the survival differences between groups. Cox regression was constructed to screen the independent risk factors. Results: A total of 439 patients were included. We identified 10% as the optimal cutoff value for positive lymph node ratio (PLNR) with X-tile software. Statistically significant differences were found in both overall survival (OS, P<0.001) and disease-free survival (DFS, P<0.001) among different PLNR groups. PLNR [hazard ratio (HR): 1.85, P<0.001] and metastatic lymph nodes along the left gastric artery (HR: 1.63, P=0.02) were the independent prognostic factors for OS. While PLNR (HR: 1.77, P<0.001) and metastatic total main bronchus lymph nodes (HR: 2.78, P=0.047) were the independent prognostic factors for DFS. Conclusions: We discovered that higher PLNR is associated with poorer OS and DFS of locally advanced ESCC. The lymph nodes along the left gastric artery and the total main bronchus lymph nodes were independent prognosticators for OS and DFS, respectively.
