1 · What the graph read from it

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.

2 · The registry

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

introductionThe impact of the new potassium binder sodium zirconium cyclosilicate (SZC) on the real-world management of acute hyperkalemia remains unknown. The aim of this study was to evaluate changes in treatment strategies and clinical outcomes for acute hyperkalemia following the approval of SZC in Japan.

methodsWe conducted a retrospective cohort study using the RWD database, a nationwide electronic medical record and claims database in Japan, including adult patients who were hospitalized with hyperkalemia (serum potassium ≥5.5 mmol/L) between April 2015 and December 2024. Using an interrupted time-series analysis, we evaluated changes in outcomes following SZC approval in April 2020. The post-approval period was stratified to distinguish the effects of the coronavirus disease 2019 (COVID-19) pandemic. The primary outcome was the monthly proportion of patients receiving renal replacement therapy (RRT). Secondary outcomes included in-hospital mortality, intensive care unit (ICU) admission, and maintenance hemodialysis initiation.

resultsOverall, 38,540 hospitalizations were included. While no significant immediate change in RRT use occurred upon SZC approval, a significant decreasing trend was subsequently observed (slope change, -0.7% per month; 95% confidence interval [CI], -1.2 to -0.1%). This downward trend in RRT use was highly pronounced after the COVID-19 pandemic ended. A significant decreasing trend in ICU admissions was observed in the post-pandemic period (slope change, -4.2% per month; 95% CI, -6.6 to -1.7%). Trends of in-hospital mortality and maintenance hemodialysis initiation did not significantly change.

conclusionsFollowing SZC approval, a decreasing trend in the use of RRT for acute hyperkalemia was observed, along with a post-pandemic decrease in ICU admissions. These trends were not accompanied by an observable increase in in-hospital mortality or initiation of maintenance hemodialysis.
