Predictors and Outcomes of In-Hospital Cardiac Arrest in University Medicine with Advanced Tertiary and Transplant Care.
Article in Medical sciences (Basel, Switzerland), 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
BACKGROUND/
objectivesIn-hospital cardiac arrest (IHCA) remains associated with poor survival, while the contribution of arrest etiology and early physiological markers to outcome remains incompletely defined. We examined associations between clinical, neurological, metabolic, and etiological factors and sustained return of spontaneous circulation (ROSC) lasting >20 min, 28-day survival, and 60-day mortality.
methodsThis retrospective single-center cohort included 134 adults with confirmed IHCA requiring cardiopulmonary resuscitation at a tertiary university hospital with advanced transplant care between 2011 and 2015. Sustained ROSC and 28-day survival were analyzed using parsimonious Firth penalized logistic regression models, and 60-day mortality using Cox proportional hazards regression. Selected neurological and biomarker analyses were considered exploratory.
resultsSustained ROSC was achieved in 91 patients (67.9%), 33 (24.6%) survived to day 28, and 30 (22.4%) survived to day 60. Initial non-shockable rhythm was associated with lower odds of sustained ROSC (aOR 0.26, 95% CI 0.09-0.69) and 28-day survival (aOR 0.27, 95% CI 0.10-0.68), and with higher 60-day mortality (aHR 1.96, 95% CI 1.25-3.08). The presence of a potentially reversible cause was associated with more favorable outcomes, whereas active hematologic malignancy was associated with higher 60-day mortality (aHR 1.89, 95% CI 1.15-3.10). Exploratory analyses also showed associations of initially dilated pupils with lower 28-day survival and higher lactate with 60-day mortality. Among patients who survived beyond 24 h, higher BNP was associated with subsequent mortality.
conclusionsNon-shockable rhythm and the presence of a potentially reversible cause were consistently associated with outcomes following IHCA, while active hematologic malignancy was associated with poorer longer-term survival. Exploratory findings from lactate, initial pupillary assessment, and BNP may provide complementary prognostic information, although the BNP analysis was limited to patients who survived beyond 24 h. These findings require confirmation in contemporary multicenter cohorts and do not establish validated clinical prediction tools.
