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 potential advantage of laparoscopic gastrectomy (LG) compared with open gastrectomy (OG) for serosa-invasive (pT4a) Siewert type II and III adenocarcinoma of the esophagogastric junction (AEG) remains uncertain. Thus, the purpose of this study was to investigate the short- and long-term outcomes of LG compared to OG for pT4a Siewert type II/III AEG cancers.

methodsWe retrospectively evaluated 283 patients with pathological confirmed T4a Siewert type II and type III AEG who underwent LG or OG in our center between January 2004 and September 2015. The short- and long-term outcomes were compared between the groups using a 1:1 matched propensity score matching method (PSM).

resultsThe LG group had a longer operation time, less estimated blood loss, less time to first flatus, less time to start liquid diet, less time to first ambulation, and shorter length of incision than the OG group. The conversion rates were 5.4% in the LG groups. There was no significant difference in the overall complication rate between the LG and OG groups. The 5-year overall survival (OS) and the 5-year disease-free survival (DFS) were comparable between the LG and OG groups (35.4% vs 32.1%, p = 0.541; 34.1% vs 31.0%, p = 0.523, respectively). There was no significant difference in the recurrence rate and pattern between the LG and OG groups.

conclusionsLaparoscopic gastrectomy is associated with better short-term outcomes and similar long-term outcomes for pT4a Siewert type II/III AEG. This study reveals that LG could be a safe and feasible option for pT4a Siewert type II/III AEG compared to OG.
