Determinants of Acute Kidney Injury After Endoscopic Retrograde Cholangiopancreatography in Patients With Liver Cirrhosis: Retrospective Observational Study.
Observational study in JMIR medical informatics, 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
backgroundPatients with cirrhosis may have acute kidney injury (AKI) after receiving endoscopic retrograde cholangiopancreatography (ERCP).
objectiveThis study aimed to identify determinants of AKI that require dialysis following ERCP in patients with cirrhosis.
methodsData from the US Nationwide Inpatient Sample from 2016 to 2020 were retrospectively reviewed. Patients aged ≥20 years with liver cirrhosis who underwent ERCP were identified. The primary outcome was AKI requiring dialysis. Logistic regression with stepwise selection was used to identify factors associated with dialysis-requiring AKI among demographic variables, comorbidities, and hospital characteristics.
resultsData from 6748 patients with liver cirrhosis who underwent ERCP were analyzed, and 2.2% (n=148) developed AKI that required dialysis. After adjustment, the results showed that decompensated liver cirrhosis (adjusted odds ratio [aOR] 4.73, 95% CI 3.12-7.15; P<.001), chronic kidney disease (aOR 5.93, 95% CI 4.00-8.79; P<.001), obesity (aOR 1.65, 95% CI 1.05-2.59; P=.03), and sepsis (aOR 3.57, 95% CI 2.44-5.23; P<.001) were significant factors associated with AKI that required dialysis. The developed model demonstrated good calibration and discrimination (c-index: 0.826 for derivation cohort, 0.824 for validation cohort).
conclusionsDecompensated liver cirrhosis, preexisting chronic kidney disease, obesity, and sepsis are significant factors associated with AKI that require dialysis following ERCP in patients with liver cirrhosis. These findings can inform risk stratification and management strategies to improve outcomes in this high-risk population.
