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 incidence of gastric cancer increases in elderly patients worldwide, laparoscopic gastrectomy (LG) for elderly patients with gastric cancer is also increasing. However, whether LG is an optimal surgical modality for elderly patients with gastric cancer remains unclear. This study aimed to evaluate the technical and oncological safety of LG for elderly patients ≥ 80 years old with gastric cancer.

methodsPatients who received curative gastrectomy for gastric cancer from 2003 to 2015 were enrolled in the study. They were divided into the LG in elderly patients aged over 80 years (LG-E) group, open gastrectomy (OG) in elderly patients (OG-E) group, and LG in non-elderly patients < 80 years (LG-NE) group. Patients' demographics and short- and long-term outcomes, such as postoperative complications and 5-year survival rate, were compared between the three groups, retrospectively.

resultsThe LG-E, OG-E, and LG-NE groups comprised 45, 43, and 329 patients, respectively. In the comparison between the LG-E and OG-E groups, the incidence of distal gastrectomy (DG) and the proportions of patients with pathological tumor stage T1, pathological N0, and final stage I were significantly higher in the LG-E versus OG-E group (89 vs. 56%, 76% vs. 16%, 82% vs. 37%, and 84% vs. 35%, p < 0.01, respectively). Blood loss and the incidence of overall postoperative complications in the LG-E group were significantly lower than those in the OG-E group (40 vs. 240 g, p < 0.01, and 29% vs. 53%, p < 0.05, respectively). Although the 5-year overall survival (OS) rate was not significantly different between the two groups, the 5-year disease-specific survival (DSS) rate was significantly higher in the LG-E group versus OG-E group (93% vs. 78%, p < 0.05). Overall comorbidities were significantly higher in the LG-E group versus LG-NE group, but there were no significant differences in short-term outcomes between the two groups. Further, although the 5-year OS rate was significantly lower in the LG-E group versus LG-NE group (67% vs. 87%, p < 0.01), there was no significant difference between the two groups in 5-year DSS rate.

conclusionLG is technically and oncologically safe for the treatment of gastric cancer in both elderly patients aged ≥ 80 years and the non-elderly and can be an optimal surgical modality for elderly patients with gastric cancer.
