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
BACKGROUND AND
aimRecently, several studies have demonstrated the safety and feasibility of laparoscopic and endoscopic cooperative surgery for duodenal tumors (D-LECS). However, the standard procedure for D-LECS has not been established. Herein, we introduce the feasibility and safety of a surgical strategy based on tumor characteristics and location in D-LECS.
methodsThis retrospective single-center study included 17 consecutive patients with duodenal tumors who underwent D-LECS between October 2017 and November 2023.
resultsTwo, 13 and 2 tumors were located in the first, second and third portions of the duodenum, respectively. Three tumors were protruded type and 14 were superficial type. The median tumor size was 25 (6-45) mm. Supracolic, mesenteric and inferior approaches were employed in 14, 2 and 1 case, respectively, during D-LECS. Laparoscopic reinforcement after endoscopic submucosal dissection (ESD) (D-LECS with ESD), laparoscopic suturing after full-thickness resection (FTR) (D-LECS with FTR) and Closed-LECS were performed in 13, 2 and 2 cases, respectively. The median operation time and blood loss were 237 (159-420) min and 0 (0-75) ml, respectively. En-bloc pathological curative resection was achieved in all cases. Two patients had paralytic ileus and delayed gastric emptying as postoperative complications. The median duration of postoperative hospital stay was 10 (6-22) days. One local recurrence was observed in a case of adenocarcinoma in situ during the median follow-up of 13 (2-71) months.
conclusionsThe feasibility and safety of our surgical strategy based on the tumor characteristics and location were demonstrated in D-LECS.
