Adrenal Medullary Nodules in Beckwith-Wiedemann Syndrome Resemble Extra-Adrenal Paraganglia.

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
Clues to mechanisms regulating development and tumorigenesis may be provided by studies of unusual diseases. Beckwit-Wiedemann syndrome (BWS) is a rare congenital disorder apparently related to abnormal regulation of insulin-like growth factor-2 (IGF-2) production. IGF2 mRNA has been previously localized to the chief cells of extra-adrenal paraganglia and to adult, but not fetal, adrenal medulla. Expression of IGF-2 by neuroblastomas has been hypothesized to reflect extra-adrenal paraganglionic differentiation. In the adrenals of a fetus with 8W5, we have observed both increased numbers of chromaffin cells and organoid nodules resembling extra-adrenal paraganglia. Immunoreactive IGF-2 was observed in both cell types, but was also observed in chromaffin cells in the normal fetal adrenal. The findings suggest autocrine or paracrine influences of IGF-2 in regulating the number and phenotype of cells derived from sympathoadrenal precursors in the developing adrenal medulla as well as in extra-adrenal paraganglia. These results have implications for the interpretation of data from neuroblastoma studies.
