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

backgroundAs the population of Japan continues to age rapidly, an increasing number of patients aged ≥ 80 years are undergoing surgery for gastric cancer. Although minimally invasive techniques have improved surgical safety, operative risks in the super-elderly population (≥ 85 years) remain a significant concern.

methodsThis retrospective, single-center study analyzed 72 patients aged ≥ 80 years who underwent gastrectomy for gastric cancer at our hospital between January 2014 and August 2024. Patients were stratified into two groups: the super-elderly group (≥ 85 years, n = 26) and the younger-elderly group (80-84 years, n = 46). Clinical characteristics, perioperative outcomes, and postoperative complications were compared between the two groups. A p-value of < 0.05 was considered statistically significant.

resultsThe mean age was 83.7 (range: 80-93) years. Comorbidities were common, particularly cardiovascular disease (19.4%) and diabetes mellitus (27.8%). Compared with the younger-elderly group, the super-elderly group had a longer preoperative hospital stay (5.8 vs. 4.5 days) but a shorter overall hospital stay (14.3 vs. 21.1 days). Minimally invasive surgery was less frequently performed in the super-elderly group (42.3% vs. 56.5%). Postoperative complications of Clavien-Dindo grade ≥ 2 occurred in 40.3% of all patients, with a lower incidence in the super-elderly group (34.6% vs. 43.5%). Mortality from non-cancer-related causes did not differ significantly between the groups.

conclusionsWith appropriate preoperative optimization, gastrectomy can be performed safely in patients aged ≥ 85 years. Individualized treatment strategies that account for comorbidities are essential for achieving favorable outcomes in this expanding population.
