Hyperammonemia-Associated Delirium Mimics Dementia: A Case Report.
Article in Psychiatry and clinical psychopharmacology, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Ammonia is considered to be a neurotoxin that affects various physiological pathways, including energy metabolism, mitochondria function, and inflammatory response. Dysfunctions of these pathways contribute to the development of cognitive and executive function impairments. A case of a 67-year-old female patient who presented with unusual features of delirium after spine surgery was reported in this study. The patient initially developed acute hepatitis, and 3 weeks later, liver functions gradually improved. However, the acute onset of cognitive impairment and mild hyperammonemia was found. The patient mainly presented with cognitive deficits and impairment of executive functions without a fluctuating course. Her cognitive impairment was resolved when the serum ammonia level returned to the normal range. Consequently, we considered the diagnosis for this patient was delirium rather than a major neurocognitive disorder (dementia). Thus, the clinical diagnosis for delirium and etiologies are discussed.
