Multiple electrolyte imbalances in hospitalized patients: a multimorbidity perspective from a large, retrospective cohort study.
Article in Annals of medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
introductionMultiple electrolyte imbalances (MEIs) are underexplored in hospitalized patients. We aimed to determine: (1) the prevalence and prognostic impact of MEIs; (2) the associations between electrolyte imbalance (EI) combinations and adverse outcomes; and (3) the potential interactions among EI types. MATERIALS AND
methodsHospitalized patients at Peking Union Medical College Hospital were enrolled from 2015 to 2020. Adverse outcomes included in-hospital mortality or discharge against medical advice. Multivariable logistic regression models were used to evaluate the associations of number of EIs, EI types, and their combinations with adverse outcomes and to calculate the population-attributable fractions (PAFs). The additive and multiplicative interactions were examined for each EI combination.
resultsAmong 324,056 hospitalizations, the prevalence of MEIs was 18.8%. Compared to patients without EIs, the odds ratios (ORs) for adverse outcomes were 2.18 (95% confidence interval [CI]: 1.83-2.59) for patients with 1 EI and 17.34 (95% CI: 15.32-19.62) for those with ≥2 EIs. The highest-risk EI combinations at the individual level were hypercalcemia-hypernatremia (OR = 14.96 [95% CI: 11.34-19.68]), hyponatremia-hypernatremia (13.00 [95% CI: 10.09-16.74]), and hypochloremia-hypernatremia (11.06 [95% CI: 8.51-14.34]), while hypokalemia-hypernatremia (PAF = 17.89% [95% CI: 17.37%-18.41%]), hyperchloremia-hypernatremia (15.29% [95% CI: 14.99%-15.59%]), and hypocalcemia-hypernatremia (12.40% [95% CI: 11.94%-12.86%]) contributed the most to adverse outcomes at the population level. Synergistic additive interactions were observed for hyperchloremia-hypernatremia (relative excess risk due to interaction = 4.80 [95% CI: 3.05-6.55]) and hypercalcemia-hypernatremia (6.98 [95% CI: 3.11-10.86]).
conclusionsMEIs are common and harmful in hospitalized patients. Prioritizing different intervention targets at individual and population levels may improve clinical outcomes.
