Important Note: Redirection of Services to ChiCTR

We would like to inform you that the Clinical Trial Registry page will discontinue the function of updating trial information directly on this platform. However, you will still be able to view the existing registration details. For any updates to trial information, you can use the China Clinical Trial Registry (ChiCTR) directly at https://www.chictr.org.cn. This change will be fully implemented by 2024-Aug-05. Thank you for your attention.
