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
objectivesSome researchers are concerned that the performance of pancreatic resection in cases of low malignancy with distal localization will increase, resulting in the occurrence or worsening of post-operative glucose intolerance. Herein, we retrospectively investigated the relationship between the pancreatic resection ratio and post-operative glucose intolerance in distal pancreatectomy (DP).
methodsTotal 135 patients who underwent DP at our hospital and were followed up for > 12 months between January 2013 and December 2022 were included. Of these, 52 patients were included, excluding those with pre-operative diabetes and those who underwent pancreatectomy using other than a stapling device. The pancreatic resection ratio (%) was measured using pancreatic volumetry by manually tracing the pancreatic area on computed tomography images obtained before and after surgery and the relationship with post-operative glucose intolerance was investigated.
resultsAmong the 52 patients, 13 (25.0%) showed post-operative worsening of glucose tolerance (impaired glucose tolerance [IGT] group). The pancreatic resection ratios were 51.1% and 34.8% in the IGT (13 patients) and non-IGT groups (39 patients), respectively (p = 0.0027). The cut-off value for the IGT group was 46.5%. The resection site was divided into two groups as follows. One group was resected near the portal vein (portal group) and the other group was resected more caudally (caudal group). Mean pancreatic resection ratios were 46.5% and 28.5% in cases of resection of the portal group (30 patients) and caudal group (22 patients), respectively (p < 0.0001). The thickness of the pancreas at the resection site was 13.1 mm in the portal group and 17.7 mm in the caudal group (p < 0.0001) and the incidence of pancreatic fistula was 6.7% and 9.1%, respectively (p = 0.7472). The incidence of post-operative glucose intolerance was 40.0% (12/30) in the portal group and 4.5% (1/22) in the caudal group (p = 0.0016).
conclusionIn cases of low-grade tumors and benign disease, pancreatic resection with preservation of the remaining pancreatic volume should be considered whenever possible.
