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

backgroundIntracorporeal mechanical gastrogastrostomy (IMG) techniques have recently been developed and their short-term safety was presented in their initial evaluation. However, whether they are comparable to extracorporeal hand-sewing gastrogastrostomy (EHG) remains unclear. The aim of the study is to establish the safety of IMG in totally laparoscopic pylorus-preserving gastrectomy (TLPPG) compared to EHG in laparoscopy-assisted pylorus-preserving gastrectomy (LAPPG).

methodsWe retrospectively analyzed the short-term outcomes of patients with middle-third early gastric cancer who underwent LAPPG or TLPPG between 2005 and 2022. The primary objective of this study was to evaluate the non-inferiority of IMG to EHG in terms of safety, with the primary endpoint being the risk difference in anastomosis-related complications (ARCs). The sample size required to achieve a statistical power of 80% for the non-inferiority test was 971 with a one-sided alpha level of 5% and non-inferiority of 5%.

resultsThe analysis included a total of 1,021 patients who underwent LAPPG or TLPPG during the study period. Among them, 488 patients underwent EHG, while 533 underwent IMG. The incidences of ARCs were 11.3% and 11.4% in EHG and IMG, respectively. The observed difference in incidence was 0.0017 (90% confidence interval - 0.0313 to 0.0345), which statistically demonstrated the non-inferiority of IMG to EHG in the incidence of ARCs. Among other complications, the incidence of wound infection in IMG was lower than that in EHG.

conclusionIMG is safe regarding ARCs compared with EHG. These results will encourage surgeons to introduce IMG for patients with early middle gastric cancer.
