Extended antibiotic prophylaxis beyond 24 h after pancreatic surgery: prevalence and risk factors.
Article in Frontiers in public health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Objective: To evaluate the compliance with antibiotic prophylaxis (AP) guidelines after pancreatic surgery, identify predictors of extended AP usage (>24 h), and assess the association between extended AP and surgical site infection (SSI). Methods: A retrospective cohort study was conducted involving 1,073 patients who underwent pancreatic surgery at the First Affiliated Hospital with Nanjing Medical University between January and December 2022. Based on the strict intent-of-use definition in the electronic medical record, patients were categorized into the AP > 24 h group ( Results: Of the 1,073 patients, 12.58% (135/1,073) received AP > 24 h. The cumulative days of postoperative AP ranged from 1 to 24, with a mean of 6.24 ± 4.09 days. While 93.20% of surgeries were performed in specialized pancreatic centers, 6.80% were performed in non-pancreatic centers. Multivariate analysis identified that surgery performed in non-pancreatic centers was an independent predictor associated with AP > 24 h (OR = 2.61, 95%CI = 1.04-6.54; Conclusion: A substantial gap between guidelines and clinical practice persists, with 12.58% of patients receiving extended AP. Surgery performed in non-pancreatic centers was identified as a significant predictor for non-adherence, with the odds of extended use being 2.61 times that of specialized centers. Given that prolonged AP was not associated with reduced SSI rates, targeted stewardship interventions are urgently needed to standardize protocols, particularly in non-specialized departments, to avoid unnecessary antibiotic exposure.
