随机方法(请说明由何人用什么方法产生随机序列):

由总中心统计学家使用专用随机数字表生成随机序列,采用中央随机化系统(基于在线登录账户与动态密码,按1:1比例动态分配) 进行分配隐藏。将PPHN患儿分配至试验组(特利加压素+常规治疗)或对照组(常规治疗)。随机序列由不参与临床操作的统计学家保管,研究者通过登录系统录入受试者基本信息后,系统自动返回分组结果,研究者无法提前获取分组信息。

Randomization Procedure (please state who generates the random number sequence and by what method):

The expert statistician (from West China Second University Hospital) will generate the allocation sequence using a computer-generated random number table with a 1:1 ratio.

本研究数据采集使用电子化病历记录表进行。研究过程中将严格保护研究参与者的隐私与数据安全。所有收集的个人信息将进行加密处理,存储在受限访问的数据库中,仅限于经过授权的研究人员使用。数据传输和存储过程中将采取必要的技术手段(如加密、访问控制等)确保数据安全。为避免任何个人信息泄露,研究数据将在收集后进行匿名化处理。所有研究参与者的身份信息将与研究数据分开存储,且仅在必要时可进行解密访问。

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

Data collection in this study will be conducted using an electronic case report form (eCRF). Throughout the research process, the privacy and data security of study participants will be strictly protected. All collected personal information will be encrypted and stored in a database with restricted access, limited only to authorized research personnel. Necessary technical measures (such as encryption and access controls) will be applied during data transmission and storage to ensure security. To prevent any disclosure of personal information, research data will be anonymized after collection. Identity information of all participants will be stored separately from the research data and will only be decrypted for access when strictly necessary.
