Impact of previous upper/lower abdominal surgery on pancreatic surgical outcomes and complications: a propensity score matching study.
Article in Langenbeck's archives of surgery, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 3 papers.
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
purposePancreatic surgery is a complex operation that has been associated with severe intraoperative and postoperative complications, especially in patients with previous abdominal surgery (PAS). Our study aimed to assess the impact of PAS on pancreatic surgery.
methodsA total of 1430 patients who underwent pancreatic surgery were included in this retrospective study and classified into the following 3 groups: previous upper abdominal surgery (PUAS) (n = 135); previous lower abdominal surgery (PLAS) (n = 161), and no history of abdominal surgery (non-PAS) (n = 1134). Using propensity score matching (PSM), patients were matched to one another at a 1:1:1 ratio with balanced baseline characteristics. Intraoperative factors, surgical complications, hospital costs, and postoperative hospitalization were collected and compared.
resultsA longer operative duration was observed in the PUAS group compared to the non-PAS group (187.54 vs. 150.50 min, p = 0.016). The intraoperative blood loss in the PUAS group was significantly higher (193.68 vs. 150.51 and 156.81 mL, p < 0.05), while the intraoperative plasma transfusion volume was higher in PLAS patients than in non-PAS patients (183.8 vs. 102.7 mL, p = 0.008). Intra-abdominal adhesions in PUAS patients were most severe, and non-PAS patients exhibited significantly lower intra-abdominal adhesion grading (p < 0.001). No significant differences were observed in postoperative complications, postoperative histopathology, postoperative hospitalization, or hospital cost.
conclusionPAS has no significant influences on surgical outcomes, and pancreatic surgery is relatively safe in this patient population. A patient history of PAS may prolong operation duration and increase intraoperative blood loss but has no impact on postoperative complications and does not increase the economic burden.
