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

backgroundEsophagectomy via left thoracotomy (the Sweet procedure) has long been the conventional route for resection of esophageal carcinoma, especially in China. However, this procedure is being increasingly critiqued, mainly regarding the lymphadenectomy. The objective of this study was to compare the Sweet procedure with the right upper mediastinal lymph node resection (MS) and Ivor-Lewis (IL) procedure in the treatment of middle or lower thoracic esophageal squamous cell carcinoma (OSCC-MLT) in terms of lymphadenectomy, postoperative complications, and long-term survival.

methodsA total of 336 OSCC-MLT patients underwent radical intent surgery (188 with MS and 148 with IL procedure) between January 2007 and September 2013 in our hospital. After propensity score matching, 129 patients from each procedure were included. The efficacy of lymph node dissection at each station was estimated by the index of estimated benefit from lymph node dissection (IEBLD).

resultsIEBLD is relatively high in stations 2L, 2R, 8, 16 and 17. The metastasis rates and ratios were similar between the MS and IL procedures at each station. The MS procedure significantly outperformed the IL procedure with a shorter operating time (212

conclusionsThe MS procedure of esophagectomy is not inferior to the IL procedure in efficiency, moreover the MS procedure is safer.
