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.
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
backgroundGastrointestinal submucosal tumors (SMTs) mostly grew in the lumen, but also some of the lesions were extraluminal, in which the stomach was the most common site. Gastrointestinal stromal tumor account for a large proportion of SMT. Due to the deep lesion location of gastric SMT, endoscopic submucosal dissection related techniques are difficult to operate, while endoscopic full-thickness resection (EFTR) has been widely used in clinical practice because it is less invasive and can preserve the physiological structure and function of the stomach. However, complete closure of the gastrectomy site after EFTR is critical. If the closure is incomplete, it may cause peritonitis, late perforation and other conditions, and even require further surgical intervention. Although there are currently a number of suture devices and techniques that can be used to promote closure, they have the problem of requiring additional equipment or being inconvenient to use. Although metal clips are widely used, their effectiveness depends on the size and tension of the defect. Therefore, an effective and convenient endoscopic closure technique is urgently needed to solve the closure problem of gastric SMTs after treatment.
aimTo investigate the effect of combined application of the preclosure technique and dental floss traction in gastric wound closure following EFTR.
methodsIn this study, the data of 94 patients treated for gastric SMTs at the Gastrointestinal Endoscopy Center of the Affiliated Union Hospital of Fujian Medical University from April 2022 to May 2023 were retrospectively analyzed. The patients were divided into a preclosure group (54 patients) and a non-preclosure group (40 patients) on the basis of the timing of wound closure with titanium clips after dental floss traction-assisted EFTR. Each patient in the preclosure group had their wounds preclosed with titanium clips after subtotal lesion resection, whereas each patient in the non-preclosure group had their wounds closed with titanium clips after total lesion resection. The lesion size, wound closure time, number of titanium clips used, incidence of postoperative complications, and postoperative hospitalization time were compared between the two groups.
resultsThe wound closure time was significantly shorter in the preclosure group than in the non-preclosure group (6.69 ± 2.109 minutes
conclusionApplication of the preclosure technique combined with dental floss traction can be used intraoperatively to effectively close the surgical wound in patients undergoing EFTR, reliably preventing the tumor from falling into the peritoneal cavity.
