Safety and efficacy of novel potassium binders for chronic hyperkalemia: a systematic review and meta-analysis of randomized controlled trials.
Review in Proceedings (Baylor University. Medical Center). 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
Objective: Hyperkalemia is a potentially life-threatening electrolyte imbalance that contributes to increased morbidity and mortality in patients with heart failure (HF) and chronic kidney disease (CKD). Novel potassium binders (NPBs) have been shown to prevent hyperkalemia; however, their efficacy and safety have not been fully established. Methods: We searched various electronic databases, including MEDLINE (via PubMed), Embase, the Cochrane Library, and ClinicalTrials.gov, to retrieve randomized controlled trials comparing NPB to placebo in patients with chronic hyperkalemia due to HF or CKD. Results: Our meta-analysis, including 12 studies involving 2517 patients, showed that NPBs, including patiromer and sodium zirconium cyclosilicate, were associated with significant mineralocorticoid receptor antagonist (MRA) optimization (relative risk [RR]: 1.28; 95% confidence interval [CI]: 1.14-1.43) as compared to placebo. The results were consistent for subgroups of sodium zirconium cyclosilicate, patiromer, CKD, and HF. NPBs also significantly reduced the incidence of hyperkalemia (RR: 0.37; 95% CI: 0.22-0.6). Additionally, NPBs reduced the mean serum potassium level from baseline as compared to placebo (mean difference: -0.46; 95% CI: -0.77 to -0.15) and MRA optimization at less than the target dose (RR: 0.62; 95% CI: 0.42-0.85). The risk of adverse events, serious adverse events, and all-cause mortality remained comparable between the two groups. Conclusion: This meta-analysis highlights the potential of NPBs to facilitate MRA optimization, reduce hyperkalemic episodes, and maintain serum potassium levels in patients with hyperkalemia, without a corresponding increase in adverse events. However, further research through large-scale studies is needed to confirm the sustained clinical benefits of NPBs, establish standardized treatment protocols, and evaluate their effectiveness across diverse patient populations with CKD and HF.
