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

Background: The necessity of the standard D2 gastrectomy for elderly patients with advanced gastric cancer (GC) is controversial because only limited data are available to demonstrate its oncological benefit for them. Our aim was to compare the outcomes of D2 and Non-D2 and to evaluate the survival benefit of D2 laparoscopic gastrectomy (LG) in elderly patients. Methods: We retrospectively identified 865 patients with GC who underwent radical LG at our hospital between 2011 and 2017. Patients aged ≥75 years who were diagnosed with clinical T1N+ or clinical T2-4 were eligible. The primary outcome was the 3-year overall survival (OS) rate. The confounding factors were minimized using propensity score matching. Results: This study included 119 patients (63 D2 LG and 56 Non-D2 LG), and 52 patients (26 each for D2 LG and Non-D2 LG) were analyzed after matching. Although no significant difference was found in overall major complications (P=1.00), complications tended to occur in the D2 group (D2 Conclusions: This study demonstrated the possible association between D2 LG and increased complication rate and no survival benefit of D2 LG in elderly patients.
