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

backgroundThe upper gastric body is of particular interest in relation to gastrectomy because this area includes a border; that is, both distal and proximal gastrectomy for early gastric cancer can involve this area. Laparoscopic subtotal gastrectomy (LsTG) is reported to be suitable procedure compared with laparoscopic proximal and total gastrectomy (LPG, LTG), regarding postoperative nutritional status and surgical safety. However, whether LsTG is an oncologically acceptable procedure for early gastric cancer in the upper gastric body is unclear.

methodsWe analyzed 215 patients with cT1N0M0 gastric cancer limitedly located in the upper gastric body. The frequency of conversion from each intended procedure to an alternative procedure, the width of the pathological margin, the incidence of lymph node metastasis at each station and the 3-year overall survival (OS) and relapse-free survival (RFS) were evaluated.

resultsLsTG was planned for 65 patients, and LPG for 72 and LTG for 78, respectively. Conversion to other procedures was required in about 10% of patients for whom LsTG or LPG was planned. The width of the pathological margin in patients who underwent LsTG was significantly shorter than patients who underwent the others. No patients who underwent LsTG, LPG or LTG had metastases in station no. 2 or 4sa lymph node. The 3-year OS and RFS rates of patients for whom each procedure was planned were not different.

conclusionsLsTG could be an oncologically acceptable procedure for cT1N0M0 gastric cancer in the upper gastric body. LsTG could be one option for such disease.
