Acute Psychosis in the Setting of Undiagnosed Normocalcemic Hyperparathyroidism: A Case Report.
Article in Cureus, 2023. 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
Hyperparathyroidism (HPT) causes an elevation of parathyroid hormone (PTH). This can result in elevated calcium levels, which can cause bone, kidney, muscle, gastrointestinal, and neuropsychiatric symptoms, including psychosis. Our report presents a unique case of an elderly woman who presented to the emergency department in an unconscious state with a working diagnosis of metabolic encephalopathy secondary to sepsis and urinary tract infection. Despite fluids and antibiotic treatment, the patient showed hallucinations. The acuteness of her psychotic episodes prompted the medical team to further investigate the cause of her hallucinations. Additional labs revealed HPT, which she had never been diagnosed with prior to the hospital admission. Our patient's novel clinical presentation revealed elevated PTH and normal calcium levels as the cause of her psychosis. We determined that the normal calcium levels were due to the patient's calcium loss secondary to acute kidney injury. Cinacalcet administration showed resolution of the patients' hallucinations, highlighting the importance of PTH screening even in normocalcemic patients. In this report, we present a rare clinical presentation of acute psychosis in the setting of undiagnosed normocalcemic HPT.
