The association between the sodium-potassium ratio and ICU mortality in cardiac arrest patients: an analysis of the eICU database.
Article in Frontiers in medicine, 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: Electrolyte imbalance, particularly abnormalities in potassium and sodium homeostasis, represents an important and potentially modifiable risk factor for in-hospital cardiac arrest. Severe disturbances in potassium or sodium levels can precipitate fatal arrhythmias and are associated with poor outcomes following resuscitation. Timely correction of these electrolyte disorders may therefore reduce mortality in patients with cardiac arrest. Although the urine sodium-potassium (Na Methods: We screened 4,085 ICU-admitted cardiac arrest patients from the eICU-CRD databases, stratified by Na Results: A total of 4,085 patients met the inclusion criteria, including 2,392 males, with a mean age of 63.7 years. A U-shaped association was observed between the Na Conclusion: To summarize, we identified a marked U-shaped relationship between the serum Na
