Effect of Broad-Spectrum Antibiotic Prophylaxis on Post-Pancreatoduodenectomy Infectious Complications: Nationwide Inpatient Database Study in Japan.

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: Despite improvements in surgical techniques and perioperative management, the incidence of postoperative surgical site infection after pancreatoduodenectomy remains high. This study aim to assess whether broad-spectrum antibiotic prophylaxis can reduce complications after pancreatoduodenectomy compared with standard care antibiotics. Methods: Data of patients who underwent pancreatoduodenectomy between July 2010 and March 2022 were extracted from a nationwide Japanese inpatient database. First- and second-generation cephalosporins were designated as narrow-spectrum, and third- and fourth-generation cephalosporins and piperacillin-tazobactam as broad-spectrum antibiotics. Patients who received either narrow- or broad-spectrum antibiotics on the day of surgery were included in the analysis. Using propensity-score stabilized inverse probability of treatment weighting, the postoperative complications were compared between patients who received antimicrobial prophylaxis with narrow-spectrum antibiotics versus broad-spectrum antibiotics. Results: From among 45 099 eligible patients, 36 742 (81.5%) and 8357 (18.5%) patients received narrow- and broad-spectrum antibiotics, respectively. After stabilized inverse probability of treatment weighting, the use of broad-spectrum antibiotics bore a significant association with the reduction in intra-abdominal infections [risk difference (RD), -7.4; 95% confidence interval (CI), -8.7 to -6.0], postoperative pancreatic fistula (RD, -3.0; 95% CI, -4.0 to -1.9), post-pancreatectomy hemorrhage (RD, -1.5; 95% CI, -1.9 to -1.1). The use of broad-spectrum antibiotics was also associated with a shorter postoperative length of hospital stay and lower total hospitalization costs. The proportion of Conclusions: The administration of broad-spectrum antibiotics as antimicrobial prophylaxis was associated with better in-hospital postoperative outcomes compared with narrow-spectrum in patients undergoing pancreatoduodenectomy.
