Prognostic significance of the number of lymph nodes dissection in esophageal adenocarcinoma patients.
Article in Translational cancer research, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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
backgroundEsophagectomy combined with lymphadenectomy has been considered as the preferred treatment option for esophageal cancer (EC). However, for a long time, no consensus is reached on the optimal number and scope of lymph node dissection (LND). In particular, related research on esophageal adenocarcinoma remains lacking at present. To determine the relationship between the number of LND and the prognosis for esophageal adenocarcinoma patients, this study was conducted based on the United States Surveillance, Epidemiology and End Results (SEER) database.
methodsData were extracted from esophageal adenocarcinoma patients undergoing esophagectomy from 2000 to 2016 based on the SEER database. Thereafter, the enrolled patients were divided into five groups according to the number of LND, namely, 0, 1-10, 11-20, 21-30 and >30 LNDs groups. Besides, the Kaplan-Meier product method was applied in estimating the impact of LND number on the overall survival (OS) and disease-specific survival (DSS) of patients. Moreover, the Cox proportional hazard model was employed to analyze the covariates that might affect the results.
resultsAfter adjusting for age, gender, race, grade, T stage, tumor location, tumor size and number of positive lymph nodes, differences in OS and DSS were statistically significant among those five groups, and only groups receiving >20 LNDs were related to the improved OS and DSS. Also, it was discovered that, difference in OS was of statistical significance across those five groups in the <50, ≥50 years old, male, Grade I, Grade II, Grade III, T1, T2, T3, and tumor size >4 cm subgroups.
conclusionsThe number of LND can serve as an independent prognostic factor for OS and DSS among esophageal adenocarcinoma patients. In addition, we recommend that esophageal adenocarcinoma patients should undergo LND to dissect at least 20 lymph nodes.
