The American Academy of Pediatrics stated in October that it doesn’t suggest routine use of leucovorin in youngsters who’re on the spectrum. The group cited restricted proof in its choice.
Officers on the Division of Well being and Human Providers didn’t reply to questions in regards to the present standing of leucovorin and whether or not the examine retraction would have any impression.
