Hyperkalemia and Pneumonia: A Retrospective Study on Mortality Outcomes in Southwest Missouri.
Article in Cureus, 2025. 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
backgroundPneumonia stands as a widely known contributor to hospitalization and mortality among adults in the United States. Meanwhile, disruptions in potassium homeostasis such as hyperkalemia may have an impact on in-patient mortality. This study seeks to examine the presence of hyperkalemia and its association with in-patient mortality among pneumonia patients.
methodsElectronic medical records were used to perform a retrospective observational cohort study in Southwest Missouri patients admitted to the hospital with pneumonia and/or hyperkalemia. Patients were divided into three samples: patients with pneumonia and hyperkalemia (P1), pneumonia without hyperkalemia (P2), and hyperkalemia without pneumonia (P3). The goal was to determine and compare the in-patient mortality rates of these samples.
resultsPatients with both pneumonia and hyperkalemia (P1) demonstrated the highest mortality rate, ranging from 34.25% to 42.31%, significantly surpassing rates observed in patients with pneumonia without hyperkalemia (P2) or hyperkalemia without pneumonia (P3). Notably, patients with pneumonia without hyperkalemia (P2) exhibited a mortality rate comparable to patients with hyperkalemia without pneumonia (P3).
conclusionOur study revealed that patients admitted to the hospital with pneumonia and hyperkalemia had a statistically significant increase in mortality in comparison to patients with pneumonia or hyperkalemia independently. Recognizing this association may help identify prognosis and thus guide the management of patients admitted to the hospital with both hyperkalemia and pneumonia.
