Association between potassium fluctuation and in-hospital mortality in acute myocardial infarction patients: a retrospective analysis of the MIMIC-IV database.
Article in Clinical research in cardiology : official journal of the German Cardiac Society, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
backgroundSerum potassium levels are recognized for their prognostic significance in patients presenting with acute myocardial infarction (AMI). However, the correlation between potassium level fluctuations and mortality rates among AMI patients remains unclear.
methodsA retrospective cohort study was conducted using the MIMIC-IV database, including deidentified data from patients admitted to the Beth Israel Deaconess Medical Center from 2008 to 2022. Potassium fluctuation was assessed using parameters including mean postadmission serum potassium levels (K
resultsA J-shaped correlation between serum potassium levels and the risk of in-hospital mortality was identified. Both high and low potassium levels were significantly associated with increased mortality. Specifically, K
conclusionsSerum potassium fluctuation is an independent predictive factor for in-hospital mortality among AMI patients. These findings underscore the importance of maintaining potassium homeostasis in the management of AMI, suggesting that monitoring and stabilizing potassium levels are crucial for reducing in-hospital mortality.
