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

This study aims to compare the short-term outcomes after minimally invasive gastrectomy between obese and non-obese population. Our analysis included data of 713 patients from ten departments of surgery. They were divided in non-obese group and obese group with 617 and 96 patients respectively. Significant differences were found in terms of mortality at 90 days (obese: 0 vs non-obese: 27, p = 0.037). Intraoperative data showed no significant differences in terms of conversion (obese: 4 vs non-obese: 43, p = 0.303). About postoperative complications, significant differences between the two groups were found only in terms of surgical infection (obese: 13 vs non-obese: 38, p = 0.009). About oncological outcomes, no differences were found about retrieved lymph nodes (obese: 30.71 ± 18.44 vs non-obese: 32.93 ± 17.62, p = 0.596) and about surgical radicality (R0) (obese:94 vs non-obese:594, p = 0.415). Obesity doesn't worsen postoperative outcomes and minimally invasive gastrectomy in obese patients is related to a lower postoperative mortality.
