Cystic fibrosis associated with Wernicke's encephalopathy in an older adult.

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
Here we report the first case of an association between cystic fibrosis and Wernicke's encephalopathy. The patient had a history of cystic fibrosis diagnosed in her early 60s associated with pancreatitis and chronic lung disease. She presented with a traumatic hip fracture requiring operative repair. On examination, she was found to have bilateral nystagmus. MRI revealed enhancement of the mammillary bodies. Laboratory results were notable for thiamine deficiency, which in context of the radiographic and physical examination findings, confirmed a diagnosis of Wernicke's encephalopathy. The cause of her low thiamine was thought to be poor dietary intake, weight loss and malabsorption associated with exocrine pancreatic insufficiency in the setting of a history of recurrent pancreatitis. The patient had complete resolution of her symptoms with the initiation of thiamine supplementation and pancreatic enzymes. Although classically associated with fat soluble vitamin deficiencies, there are increasing reports of water-soluble vitamin deficiencies associated with cystic fibrosis.
