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
purposeDiarrhea after pancreatic surgery is gaining growing importance since extended pancreatic resections have been increasingly performed. The aim of this study was to determine the incidence of diarrhea after pancreatic surgery with a special focus on the extent of resection and subgroups at higher risk for diarrhea.
methodsRetrospectively collected data of all consecutive patients undergoing pancreatic surgery between 01/2021 and 11/2023 were analyzed. Information on bowel movements was prospectively documented. Diarrhea was defined as > 3 bowel movements per day for at least 72 h despite pancreatic enzyme replacement and in the absence of laxatives or prokinetics. Extended resections were differentiated according to the type of vascular resection and arterial divestment. Clinicopathological characteristics and outcomes were compared among these groups and risk factors for diarrhea were identified.
resultsA total of 320 patients were included. Following any type of pancreatectomy, 71/320 (22.2%) patients developed diarrhea. The incidence of diarrhea after partial pancreatoduodenectomy, distal pancreatectomy and total pancreatectomy was 26.6%, 11.5% and 35.3%, respectively (p = 0.004). Arterial divestment/resection and venous resection were significantly associated with an increased risk for postoperative diarrhea in 87% (OR = 31.14; 95%-CI: 8.77, 170.08; p < 0.001) and 52.2% of patients (OR = 5.14; 95%-CI: 2.51, 10.52; p < 0.001), respectively. Postoperative diarrhea was significantly associated with a prolonged length of hospital stay (19 vs. 13 days; 95%-CI: 3.00, 7.00; p < 0.001).
conclusionDiarrhea after pancreatic resection is a common postoperative complication affecting especially patients undergoing extended resections with vascular resections and arterial divestment. Diarrhea significantly impairs postoperative recovery leading to a prolonged hospital stay.
