Intensive Care Medicine Retracts Letter Over Nonexistent References

Intensive Care Medicine retracted a December 2024 letter after editors found that 10 of its 15 references could not be located, including one cited as published in the same journal. Springer Nature added an editor's note on November 4 and the editor-in-chief formally retracted the letter on November 29 after concluding generative-AI formatting produced inaccurate citations. The case highlights verification and peer-review lapses flagged in January 2025.
