1 · What the graph read from it

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.

2 · The registry

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

Octreotide is considered a second-line treatment for congenital hyperinsulinism unresponsive to diazoxide. Necrotizing enterocolitis (NEC) is a serious adverse effect of octreotide, typically occurring in a dose-dependent manner. Here, we report a case of necrotizing enterocolitis following a single administration of a very low dose of octreotide. A female infant was admitted on day 3 of life with severe hypoglycemia. Laboratory findings revealed hyperinsulinemia and hypoketotic hypoglycemia, confirming a diagnosis of congenital hyperinsulinism. Despite diazoxide therapy, adequate glycemic control was not achieved. As a second-line intervention, a single subcutaneous injection of octreotide (1.6 μg/kg) was administered. Two days post-administration, the patient developed abdominal distension and significant vomiting. NEC was diagnosed, necessitating bowel decompression surgery. Subsequent 18F-DOPA positron emission tomography/computed tomography revealed a focal lesion extending from the pancreatic head to the body. The lesion was successfully resected with preservation of nearly the entire normal pancreas. This case highlights that even a very low dose of octreotide may precipitate necrotizing enterocolitis, warranting close monitoring. Lesion localization using 18F-DOPA positron emission tomography/computed tomography is critical in guiding surgical management of congenital hyperinsulinism.
