Long QT syndrome and hypoglycemia in a postbariatric surgery patient with a likely pathogenic variant in
Article in JCEM case reports, 2026. 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
A 41-year-old woman with history of hypoglycemic symptoms underwent sleeve gastrectomy for weight loss. Her postoperative course was complicated by cardiac arrest due to polymorphic ventricular tachycardia arising from QT interval prolongation. Weeks after surgery, hypoglycemic symptoms worsened, with postprandial capillary glucose as low as 33 mg/dL (SI: 1.2 mmol/L) (reference, 70-140 mg/dL [SI: 3.9-7.8 mmol/L]). An inpatient fast indicated appropriate suppression of insulin. The combination of worsening hypoglycemia early postoperatively and prolonged QT interval prompted genetic testing, which revealed a likely pathogenic variant in
