Cardiac Arrests During Inpatient Gastrointestinal Endoscopic Procedures: A United States Nationwide Assessment.
Article in Digestive diseases and sciences, 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
backgroundMajor cardiac events can complicate endoscopic procedures. However, the true incidence and outcomes of these events are not well defined.
aimsWe aimed to define the true incidence of cardiac arrest during inpatient endoscopic procedures and the associated outcomes.
methodsWe performed a cross-sectional retrospective analysis of the National Inpatient Sample from 2016 to 2023. Endoscopic intraprocedural cardiac arrests were identified using ICD-10 diagnostic and procedural codes. Multivariable logistic regression was used to assess patient and procedural factors associated with cardiac arrest. Outcomes among patients experiencing endoscopic intraprocedural cardiac arrest were compared with those of all other cases of in-hospital cardiac arrest.
resultsAmong 11,137,008 inpatient endoscopic procedures, 1,110 were complicated by cardiac arrest, corresponding to one cardiac arrest per 10,125 procedures. Among assessed patient factors, congestive heart failure had the strongest association with cardiac arrest (aOR = 2.78, 95% CI 2.04-3.78; p < 0.001). Compared with upper endoscopy, colonoscopy was associated with a lower risk of cardiac arrest (aOR = 0.50, 95% CI 0.36-0.69; p < 0.001), while endoscopic retrograde cholangiopancreatography had a similar risk (aOR = 0.75, 95% CI 0.49-1.15; p = 0.183). In-hospital mortality was lower among patients with endoscopy-associated cardiac arrest compared with other cases of in-hospital cardiac arrest (30.6% vs. 71.0%; aOR-0.17, 95% CI 0.13-0.23; p < 0.001).
conclusionsIntraprocedural cardiac arrest is an uncommon complication of inpatient endoscopy. Upper endoscopy carries a higher risk than colonoscopy, and patients with congestive heart failure are at increased risk. Outcomes following endoscopy-associated cardiac arrest are more favorable than for other in-hospital cardiac arrests.
