Predictors of hemodynamic instability during ERCP sedation in older adults: impact of sedation strategy in a retrospective cohort.
Article in BMC geriatrics, 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
backgroundOlder adults undergoing endoscopic retrograde cholangiopancreatography (ERCP) are particularly vulnerable to sedation-related hemodynamic instability. This study aimed to evaluate predictors of hemodynamic instability and the association between sedation strategy and hemodynamic outcomes in elderly patients.
methodsThis retrospective cohort study included patients aged ≥ 65 years who underwent ERCP under deep sedation between 2015 and 2025. Hemodynamic instability was defined as either a ≥ 30% reduction in mean arterial pressure or vasopressor requirement. Multivariable logistic regression and inverse probability of treatment weighting (IPTW) were performed.
resultsA total of 150 patients were included, and hemodynamic instability occurred in 46 (30.7%). Advanced age, ASA class III-IV, lower baseline mean arterial pressure, and prolonged procedure duration were associated with increased instability risk. Ketofol use was associated with lower odds of hemodynamic instability than propofol alone (aOR: 0.50, 95% CI: 0.25-0.99, p = 0.047), with consistent findings after IPTW (OR: 0.55, 95% CI: 0.31-0.98, p = 0.043).
conclusionsHemodynamic instability is common during ERCP in older adults. Ketofol use was associated with lower observed hemodynamic instability; however, residual confounding cannot be excluded because of the retrospective non-randomized design. CLINICAL TRIAL REGISTER: Not applicable.
