Prophylactic supraclavicular lymph node dissection for esophageal squamous cell carcinoma: a systematic review and meta-analysis.

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
The supraclavicular lymph nodes (SCLNs) have been regarded as regional nodes for esophageal squamous cell carcinoma (ESCC) in Japan and eastern Asian countries, whereas their involvement has been regarded as distant metastasis in Western countries. The importance of thorough dissection of the lymphatic chain along the recurrent laryngeal nerve, including the cervical paraesophageal nodes, has become well understood; therefore, the contemporary clinical question is whether prophylactic SCLN dissection (SLND) in addition to cervical paraesophageal node dissection is beneficial for patients with ESCC. We analyzed studies comparing esophagectomy with SLND vs. esophagectomy without SLND, in both of which cervical paraesophageal node dissection had been completed, based on a comprehensive literature search of the PubMed, Scopus, and Cochrane databases. Our meta-analysis focused on two long-term outcomes: 3-year and 5-year overall survival (OS) rates; and three short-term outcomes: pneumonia, recurrent nerve palsy, and anastomotic leakage. Four studies, with a collective total of 1584 patients were included in the review. No significant differences were found between esophagectomy with SLND vs. esophagectomy without SLND in the meta-analysis of both long-term (3-year and 5-year OS; risk ratio 1.09, 95% CI 0.94-1.26, P = 0.28, and risk ratio 1.14, 95% CI 0.96-1.35, P = 0.15, respectively) and short-term outcomes. Based on our analysis, no clear data support prophylactic SLND on the cervical paraesophageal node dissection.
