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 gastrectomy (LG) is now practiced widely, but it is unclear whether LG is the appropriate approach for elderly patients with resectable advanced gastric cancer. The aim of this study was to examine whether LG is more or less advantageous for elderly patients than for young patients.

methodsWe collected data on 571 consecutive patients who underwent gastrectomy for pT2-4 gastric cancer between January 2001 and December 2015. After adjustment with one-to-one propensity score matching, short-term and long-term outcomes were compared between the LG and open gastrectomy (OG) groups among young (age < 70 years) and elderly (age ≥ 70 years) patients.

resultsThe LG group had a significantly longer operative time (P < 0.001) and less blood loss (P < 0.001) than the OG group among young and elderly patients. There were no significant differences regarding complications. Although disease-specific survival was similar between the LG and OG groups among young and elderly patients, LG was associated with more favorable overall survival than OG only among elderly patients (hazard ratio 0.67; 95% confidence interval 0.35-1.26). Death from respiratory diseases occurred more frequently in the OG group (10.9%) than in the LG group (0%) for elderly patients (P = 0.012).

conclusionLG for resectable advanced gastric cancer was not inferior to OG in terms of both short-term and long-term outcomes regardless of patient age. In elderly patients, LG may improve overall survival by reducing mortality from respiratory diseases.
