Abdominal Pain and Hyperlactatemia in Thiamine Deficiency: A Case Report.

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
An eight-year-old boy with recurrent abdominal pain, refusal to eat, gagging, and weight loss for five months experienced a sudden clinical deterioration after a gastrointestinal endoscopy with biopsy. Initially misdiagnosed with pancreatitis, he underwent hospitalization, fasting, and parenteral nutrition (PN) for 15 days. Despite this, his symptoms persisted, and serum lactate levels progressively increased. Transferred to a university hospital, abdominal beriberi was suspected, and intravenous thiamine was promptly administered. Symptoms resolved within 24 h. A review of the PN prescribed revealed the absence of thiamine, confirming the diagnosis. Healthcare professionals often associate thiamine deficiency with alcoholic adults presenting Wernicke encephalopathy; however, abdominal beriberi should also be considered in children with acute abdomen, especially when elevated serum lactate indicates impaired cellular metabolism due to thiamine deficiency.
