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

backgroundLaparoscopic radical distal gastrectomy (LDG) has been more frequently performed for locally advanced distal gastric cancer (AGC) than open distal gastrectomy (ODG). However, the benefits of LDG for elderly AGC patients (AGC-lap) remain unclear.

methodsPatients aged ≥ 70 years who underwent D2 distal gastrectomy from July 2014 to July 2021 were enrolled consecutively. Perioperative parameters, pathological features, and oncological outcomes of AGC-lap patients (n = 39) were compared with those of elderly AGC patients receiving ODG (AGC-open; n = 37) and elderly early gastric cancer patients receiving LDG (EGC-lap; n = 41) respectively.

resultsThe median age of all AGC patients was 77 years, and 28% of them had an Eastern Cooperative Oncology Group score ≥ 2. Most of the perioperative and pathological features (including the number of lymph nodes harvested) were similar between the AGC-lap and AGC-open groups. AGC-lap patients had longer median operative times (215 min versus 192 min) but significantly less surgical complications (10.3% versus 37.8%) and shorter median hospital stays (11 days versus 13 days) than did AGC-open patients (all p < 0.05). The 3-year recurrence-free and overall survival was 66.2% and 88.8% in the AGC-lap group and 51% and 66.3% in the AGC-open group (both p = 0.1). The perioperative features, including operative time, number of lymph nodes harvested, hospital stay, and complication rates, were similar between the AGC- and EGC-lap groups.

conclusionsLDG was safely and effectively performed in elderly AGC patients, resulting in faster recovery and a lower complication rate than ODG, without compromising oncological outcomes.
