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

objectiveThe purpose of this study was to detect the feasibility, safety, and effectiveness of mediastinoscopic esophagectomy for early esophageal cancer.

methodsThe clinical data of 194 patients who underwent mediastinoscopic esophagectomy for early esophageal cancer in our center from December 2005 to October 2014 were retrospectively analyzed.

resultsAll the surgery was performed successfully. The average duration of thoracic surgery was 48.2±7.8 min and the average intra-operative blood loss was 128.1±34.5 mL. An average of 3.1±1.6 lymph node stations were dissected, with an average number of dissected lymph nodes being 9.38±6.2, among which 4.2±5.4 were mediastinal lymph nodes. No peri-operative mortality was noted, and the rate of peri-operative morbidity was 13.4%. The median duration of follow-up was 39 [3-108] months, and the overall survival was 72.73%. The overall survival rates significantly differed among different T stages; more specifically, the 5-year survival was 95.23% in patients with stage T1a esophageal cancer, 70.15% for T1b, and 55.56% for T2 (P<0.001). The overall survival was significantly better in patients with negative lymph nodes than those with lymph nodes metastasis (P=0.003); more specifically, the 5-year survival rate was 84.9% for N0, 62.5% for N1, and 50.0% for N2 + N3.

conclusionsThe mediastinoscopic esophagectomy can achieve a similar effectiveness as the conventional thoracoscopic surgery for patients with early stage esophageal cancer.
