1 · What the graph read from it

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.

2 · The registry

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

purposeBoth squamous cell carcinomas and adenocarcinomas can develop in the esophagogastric junction. To clarify the appropriate lymph node dissection range, lymph node metastases from cancers in the esophagogastric junction were investigated.

methodsThe nodal metastases were analyzed in 64 patients with squamous cell carcinoma and 129 with adenocarcinoma according to Siewert's classification, which is based on topographic anatomical criteria for adenocarcinoma.

resultsThe squamous cell carcinomas located above the esophagocardial junction had more frequent metastasis to the lower and middle mediastinal lymph nodes in proportion to the depth of the tumor. Nodal metastasis was also often detected in the abdominal lymph nodes. In contrast, adenocarcinomas metastasized less frequently to the mediastinal lymph nodes, and the metastatic rates in the abdominal nodes were higher than those from squamous cell carcinoma.

conclusionEsophagectomy with mediastinal and abdominal lymph node dissection is considered to be an appropriate approach for surgical resection of squamous cell carcinomas, whereas transhiatally extended gastrectomy with lower mediastinal and abdominal lymph node dissection is recommended for the treatment of adenocarcinomas.
