Assessing the effect of single dose antibiotic prophylaxis compared with a multiday regimen in liver transplant recipients undergoing routine endoscopic retrograde cholangiopancreatography: a retrospective, single-centre, registry-based cohort study with a historical control group.

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
objectiveBiliary complications, particularly anastomotic strictures, are common after liver transplantation (LT). The recommended duration of antibiotic prophylaxis after routine endoscopic retrograde cholangiopancreatography (ERCP) for LT patients varies across international guidelines and literature. Therefore, this study aimed to evaluate the impact of a single-dose antibiotic prophylaxis on the post-ERCP cholangitis rate, overall antibiotic exposure and potential risk factors for cholangitis in this cohort.
methodsWe conducted a single-centre, registry-based, non-interventional cohort study at the Department of Gastroenterology, Heidelberg University Hospital, to investigate the impact of a newly introduced standard operating procedure (SOP) involving a periinterventional single-dose prophylaxis (SOP cohort, n=54 procedures) compared with a historical cohort (n=100 procedures) that received a multiday regimen. Following its implementation in January 2019, the SOP cohort included all routine ERCPs from January 2019 to May 2020, whereas the historical cohort comprised procedures from March 2015 to August 2017. The diagnosis and severity grading of cholangitis were based on the adapted Tokyo Guidelines.
resultsThe duration of the periinterventional antibiotic therapy differed significantly between cohorts, with a median of 0.33 days in the SOP cohort and 4 days in the historical cohort (p<0.001). Despite this reduction, there was no significant difference in the rate of post-ERCP cholangitis between the two cohorts (without dilation: 9.5% vs 17.4%, p=0.67)-even in procedures involving dilation (20.3% vs 25.8%, p=0.53). Moreover, univariate analysis did not identify any significant risk factors for the development of post-ERCP cholangitis, including the performance of dilation (p=0.32).
conclusionIn our study, a significant reduction in periinterventional antibiotic duration did not increase post-ERCP cholangitis risk, even with dilation. This suggests shorter regimens can be safely implemented.
