Reinstitution of pegvaliase therapy during lactation.
Article in Molecular genetics and metabolism reports, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Pegvaliase, an injectable form of phenylalanine ammonia lyase, is an enzyme substitution therapy for adults with phenylketonuria (PKU). Experience with pegvaliase during lactation is scarce. Limited evidence suggests that pegvaliase does not pass into breast milk. The case presented here describes the pregnancy and lactation experience of a woman with PKU who was treated with pegvaliase prior to pregnancy, discontinued pegvaliase and was treated with a phenylalanine-restricted diet in preparation for and during pregnancy, and then reinstituted pegvaliase two weeks after giving birth and throughout lactation. No pegvaliase activity was detected in pumped breast milk samples prior to reinstituting pegvaliase, and at doses of 80, 110 and 140 mg/week during lactation. The phenylalanine content of breast milk samples collected during pegvaliase therapy were not significantly different than controls, and the infant has grown and developed normally, indicating that pegvaliase therapy during lactation is safe.
