Insulinoma initially misdiagnosed as migraine.
Article in Archive of clinical cases, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Insulinoma is a rare functional neuroendocrine tumor of pancreatic islet cells that produces excessive insulin leading to neuroglycopenic and autonomic symptoms relieved by glucose. We report a case of a 39-year-old woman with recurrent neuroglycopenic symptoms for nearly five years, initially misdiagnosed as migraine, until she presented to ED with a collapse secondary to hypoglycemia. Biochemical confirmation was obtained during a supervised 72-hour fast, with symptomatic hypoglycemia which showed lowest glucose levels of 1.7mmol/L, elevated C-peptide levels of 2,271pmol/L, high insulin levels of 83.5 mU/L and a negative sulfonylurea screen. Imaging demonstrated a large hyper enhancing pancreatic mass, confirmed by
