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

objectivesEndoscopic eradication therapy is used to treat mucosal neoplasms in Barrett's esophagus, but cannot cure cancers that have metastasized to lymph nodes. The risk of such metastases has been proposed as a reason to consider esophagectomy rather than endoscopic therapy for esophageal mucosal neoplasia. The objective of our study was to determine the frequency of lymph-node metastases in patients with high-grade dysplasia (HGD) and intramucosal carcinoma in Barrett's esophagus.

methodsWe performed a systematic review using the PRISMA guidelines to identify studies that included patients who had esophagectomy for HGD or intramucosal carcinoma in Barrett's esophagus, and that reported final pathology results after examination of esophagectomy specimens.

resultsWe identified 70 relevant reports that included 1,874 patients who had esophagectomy performed for HGD or intramucosal carcinoma in Barrett's esophagus. Lymph-node metastases were found in 26 patients (1.39 % , 95 % CI 0.86 – 1.92). No metastases were found in the 524 patients who had a final pathology diagnosis of HGD, whereas 26 (1.93 % , 95 % CI 1.19 – 2.66 %) of the 1,350 patients with a final pathology diagnosis of intramucosal carcinoma had positive lymph nodes.

conclusionsThe risk of unexpected lymph-node metastases for patients with mucosal neoplasms in Barrett's esophagus is in the range of 1 – 2 %. Esophagectomy has a mortality rate that often exceeds 2 %, with substantial morbidity and no guarantee of curing metastatic disease. Therefore, the risk of lymph node metastases alone does not warrant the choice of esophagectomy over endoscopic therapy for HGD and intramucosal carcinoma in Barrett's esophagus.
