Case Report: Refractory hypokalemia as a clinical manifestation of Crooke's cell adenoma.
Article in Frontiers in medicine, 2025. 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
Crooke cell adenomas (CCA) are a rare and aggressive subtype of corticotrope tumors, with a prevalence of less than 1% pituitary adenomas, commonly manifest as Cushing's syndrome. We present the case of a 62-year-old male with progressive lower limb oedema, hypertension, and severe refractory hypokalemia. In this case, severe hypercortisolism was identified with the presence of a pituitary microadenoma of 9×6 mm and adrenal bilateral hyperplasia. Ectopic hypercortisolism was discarded after further evaluation. The patient was taken to a transsphenoidal endoscopic resection with complete resolution of symptoms. Histopathological and microscopic studies revealed findings consistent with Crooke cells compatible with Crooke cell adenoma. This tumor subtype exhibits a heterogeneous clinical presentation and is infrequently reported in the literature. Consequently, it represents an unpredictable clinical entity with a variable medical course.
