Hyperleukocytosis and Pseudohyperkalemia in a Patient With Severe SARS-COVID 19 Unmasks Chronic Lymphocytic Leukemia.
Article in Cureus, 2021. 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
Coronavirus disease 2019 (COVID-19) has caused significant morbidity and mortality in a vast majority of the patient population, especially those with malignancies. Chronic lymphocytic leukemia (CLL) is the most common leukemia in adults and is often an indolent disease. High white blood cell counts greater than 120 k/cumm in chronic lymphocytic leukemia may be implicated in cases of COVID-19. Hyperleukocytosis leads to falsely elevated potassium levels due to cell fragility. Pseudohyperkalemia occurs when elevated potassium is present due to potassium movement out of cells during or after a blood sample is drawn. Pseudohyperkalemia may be suspected when elevated potassium is present in asymptomatic patients with no corresponding electrocardiogram findings. The authors present a case of hyperleukocytosis and pseudohyperkalemia in a patient whose COVID-19 infection unmasked CLL.
