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

purposesRobotic gastrectomy (RG) offers superior dexterity and visualization compared with laparoscopic gastrectomy (LG). However, its high cost requires careful patient selection. This study aimed to evaluate whether these advantages provide clinical benefits for elderly patients who are vulnerable to surgical stress.

methodsThis retrospective study included 656 patients with gastric or esophagogastric junction cancer who underwent R0 RG or LG. The patients were stratified into elderly (≥ 75 years, n = 300) and non-elderly (< 75 years, n = 356). Propensity score matching was performed within each group to adjust baseline differences, and the outcomes were compared.

resultsIn elderly patients, RG caused fewer postoperative complications (grade ≥ III) (3.0% vs. 11.0%, P = 0.03) and lower postoperative C-reactive protein (P = 0.03) and drain amylase levels (P = 0.02). In non-elderly patients, RG led to lower drain amylase levels (P = 0.002). However, the complication rates did not differ significantly (3.8% vs. 7.6%, P = 0.29). No significant differences in the recurrence-free survival or overall survival were observed.

conclusionsRG may reduce postoperative complications in elderly patients, thus supporting a potential benefit in this population.
