Cardiovascular Outcomes and Hyperkalemia Risk in Patients With Diabetes, Chronic Kidney Disease and Heart Failure: A Real-World Comparison of Non-steroidal versus Steroidal Mineralocorticoid Receptor Antagonists.
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
backgroundSteroidal mineralocorticoid receptor antagonists (MRAs) reduce morbidity in heart failure (HF) but frequently cause hyperkalemia, limiting long-term use. Non-steroidal MRAs such as finerenone offer improved receptor selectivity, but real-world comparative data remain scarce.
methodsWe used the TriNetX Global Collaborative Network to identify adults with type 2 diabetes mellitus (T2DM), chronic kidney disease (CKD), and HF initiated on a non-steroidal (finerenone) or steroidal MRA (spironolactone, eplerenone) between January 2020 and December 2024. Propensity score matching (1:1) yielded 780 patients per cohort. Outcomes included hyperkalemia, arrhythmia, stroke, myocardial infarction (MI), and all-cause mortality.
resultsNon-steroidal MRAs were associated with significantly lower risks of hyperkalemia >5.5 mmol/L (16.0% vs 21.8%; HR 0.683, 95% CI 0.542-0.861; p=0.001) and severe hyperkalemia >6.0 mmol/L (7.6% vs 10.4%; HR 0.690, 95% CI 0.493-0.965; p=0.029). They were also linked to a lower arrhythmia incidence (31.2% vs 44.7%; HR 0.596, 95% CI 0.506-0.703; p<0.001), stroke (6.2% vs 9.9%; HR 0.606, 95% CI 0.422-0.869; p=0.006), and all-cause mortality (6.3% vs 16.5%; HR 0.359, 95% CI 0.258-0.499; p<0.001). MI was numerically lower (10.9% vs 13.5%; HR 0.762, 95% CI 0.572-1.014; p=0.061) but not statistically significant.
conclusionIn patients with T2DM, CKD, and HF, non-steroidal MRAs were associated with improved safety and cardiovascular outcomes compared with steroidal MRAs. However, the observational study design and, hence, the limitation in data that can be collected warrant cautious interpretation. Prospective randomized head-to-head trials are warranted before adaptation in clinical practice.
