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

purposeTo compare the postoperative short-term results of intracorporeal anastomosis (IA) using overlap anastomosis (OLA), with those of extracorporeal anastomosis (EA) using functional end-to-end anastomosis (FEEA) or hand-sewn anastomosis (HSA), after laparoscopic colectomy (LAC).

methodsThe subjects of this retrospective study were 208 patients with colon cancer who underwent OLA, FEEA, or HSA after LAC at our institution, between 2018 and 2021. The short-term results of the OLA group were compared with those of the FEEA and HSA groups, respectively, using a propensity score-matching method.

resultsThe mean operative time for anastomosis was longer in the OLA group than in the FEEA and HSA groups (p < 0.0001). The mean blood loss volume was less in the OLA group than in the FEEA and HSA groups (p = 0.0344 and p = 0.0002, respectively). The mean skin incision size was smaller in the OLA group than in the FEEA and HSA groups (p < 0.0001 and p = 0.0031, respectively). None of the patients in the OLA group had surgical site infections. Three to five patients were required for the surgeon to plateau on the learning curve.

conclusionAlthough IA required more time than EA, the skills appeared to improve with experience and the short-term results were superior to those of EA.
