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: Whether laparoscopic approach to gastrectomy for gastric cancer (GC) reduces the risk of pneumonia remains unknown. In this study, we compared pneumonia outcomes for patients with GC who underwent either laparoscopic gastrectomy (LG) or open gastrectomy (OG). Methods: The ACS NSQIP database was queried to identify patients with GC who underwent LG or OG between Jan 2012 - Dec 2018. Outcomes were compared using regression models. A post-hoc analysis was performed for elderly patients. Results: The study cohort included 2661 patients, 23.4 % undergoing LG. Laparoscopic approach lowered pneumonia risk (OR 0.47, Conclusions: LG in patients with GC has both statistically and clinically significant advantages over OG with respect to pneumonia. Further studies are needed to validate the relationship between postoperative pneumonia and surgical approach for gastrectomy.
