Role of point-of-care arterial blood potassium in diagnosing pseudohyperkalemia.
Article in Proceedings (Baylor University. Medical Center), 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Hyperkalemia is a life-threatening emergency, but it needs to be differentiated from pseudohyperkalemia to avoid unnecessary treatment. We present a case of pseudohyperkalemia in a chronic lymphocytic leukemia patient with severe leukocytosis, highlighting the role of point-of-care potassium. Laboratory workup showed persistent hyperkalemia on analysis of venous blood samples even after treatment for hyperkalemia. Point-of-care potassium checks on whole arterial blood immediately after sampling were consistently in the normal range. Treatments for hyperkalemia were stopped to avoid life-threatening hypokalemia.
