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 present study compared the short-term outcomes and costs of laparoscopic distal gastrectomy (LDG) with those of open distal gastrectomy (ODG) for gastric cancer using a nationwide administrative database in Japan.

methodOverall, 37,752 patients with gastric cancer who underwent distal gastrectomy at 1074 hospitals in the fiscal year 2012-2013 were evaluated using a diagnosis procedure combination database in Japan. We performed a retrospective analysis via a multilevel analysis (MLA) of the short-term surgical results and costs of the LDG and ODG groups. The models included the age, sex, comorbid complications, smoking, body mass index (BMI), activity of daily living (ADL), stage, and the number of cases of gastrectomy per facility for adjustment. The in-hospital mortality relative to the hospital volume was also compared.

resultsThe LDG group required postoperative blood transfusion less frequently and had fewer postoperative complications, shorter hospitalization, and lower operative mortality than the ODG group. While this stage did not correlate with the in-hospital mortality, the surgical method, age, sex, ADL, BMI, comorbidity, and yearly volume showed a correlation. A significant association in the in-hospital mortality was observed between low- and very-high-volume hospitals.

conclusionIn this large nationwide cohort of patients with gastric cancer using an MLA, LDG was shown to be safer with lower mortality and postoperative complication rates than ODG.
