随机方法(请说明由何人用什么方法产生随机序列): |
根据计算机生成的随机数表进行受试者分配,按1:1比例分配至试验组(自体血小板分离组,APP)和对照组(Control)。随机序列由独立统计人员使用统计软件R4.4.0预先生成并封存。 |

|
Randomization Procedure (please state who generates the random number sequence and by what method): |
Participants will be randomly assigned in a 1:1 ratio to the intervention group (autologous platelet apheresis group, APP) or the control group based on a computer-generated randomization list. The random sequence will be pre-generated and sealed by an independent statistician using R software (version 4.4.0). |

盲法: |
本研究采取部分盲法设计以降低偏倚风险。负责记录的医师负责录入患者的一般资料,并按照患者的编号提交分组信息;操作医师根据分组方案确认后实施相应的干预措施;随访医师按预定时间节点对接受干预的患者进行评估,此三位医师各自独立。由于操作医师需实施相应干预措施,因此无法对患者分组持盲。为尽量减少偏倚,患者、分组设计者、随访医师对患者的分组情况均持盲。试验过程中若因医疗需要被迫揭盲,须完整记录揭盲原因、时间、相关人员,并评估对结果的潜在影响。 |
|
Blinding: |
A partial blinding design is adopted in this study to minimize the risk of bias. The data-recording physician is responsible for entering the patient's baseline information and submitting the grouping information according to the patient’s study number. The operating physician confirms the group assignment and performs the corresponding intervention, while the follow-up physician independently evaluates patients at predefined time points. These three physicians operate independently of each other. As the operating physician must deliver the intervention, blinding to group allocation is not feasible for this role. To minimize potential bias, the patients, group assignment personnel, and follow-up physicians will remain blinded to the group allocation. In cases where unblinding is medically necessary during the study, the reason, time, personnel involved, and potential impact on study outcomes must be thoroughly documented and evaluated. |
