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
backgroundWe present a novel two hemi-purse-string suture technique for duodenal stump reinforcement in laparoscopic gastrectomy. However, the simplicity and safety of this technique have not yet been fully evaluated.
methodsRetrospectively collected data from 217 patients diagnosed with gastric cancer and underwent distal/total gastrectomy at Nanfang Hospital from April 2022 to April 2025, including 107 cases underwent the two hemi-purse-string suture and 110 cases underwent continuous inverting suture. Analyze and compare the clinicopathological information, intraoperative operation time and postoperative complications between two groups of patients.
resultsThere was no statistically significant difference in baseline data between the two groups (P > 0.05), indicating comparability. Compared to the continuous inverting suture group, patients who underwent duodenal stump reinforcement with the two hemi-purse-string technique demonstrated a significantly shorter duodenal stump suture time (298.2 ± 53.8 s vs. 326.8 ± 78.4 s, t = -3.109, p = 0.002) and required fewer stitches (4.47 ± 0.63 vs. 6.35 ± 1.37, t = -12.892, p < 0.001). Regarding the success of embedding, a successful primary embedding was achieved in 100% (107/107) of cases in the two hemi-purse-string suture group, compared to 99.1% (109/110) in the continuous inverting suture group. No cases in either group experienced duodenal serosal tearing during the reinforcement procedure. The duodenal stump embedding was completed according to the predetermined plan in all patients in both groups (107/107 vs. 110/110). Importantly, no incidents of duodenal stump leakage, pancreatic fistula, or intra-abdominal haemorrhage occurred in either group, indicating comparable safety profiles between the two techniques.
conclusionThe two hemi-purse-string suture used for duodenal stump reinforcement can shorten the suture time and has no postoperative complications such as duodenal stump fistula. It is efficient and reliable.
