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

Introduction: Severe hyperkalemia warrants immediate hospitalization for patients with acute instability. However, the benefit of inpatient care in the absence of acute instability remains poorly defined. We therefore evaluated clinical outcomes across clinical settings for these patients. Methods: This two-center retrospective cohort study included outpatients presenting with severe hyperkalemia (serum potassium level [K Results: A total of 554 patients with severe hyperkalemia were identified, comprising 276 inpatients and 278 outpatients. Median age was 75 (interquartile range [IQR] 65-83) years, 392 (71%) were male, and median K Conclusions: While outpatient management for severe hyperkalemia might be feasible for clinically stable patients in terms of short-term mortality, it carries a substantially increased risk of recurrence. Accordingly, hospitalization should generally be regarded as the preferred strategy.
