随机方法(请说明由何人用什么方法产生随机序列):

将使用交互式应答技术(IRT)集中将所有参与者随机分配至研究干预组。 通过 IRT 集中进行随机化和研究干预分配,由此生成参与者随机化表,并根据该列表为参与者分配干预编号和相应的干预药盒。 将按筛选时的年龄(<12 岁;>=12 岁)、HbA1c(<8.5%;>=8.5%)和随机 C 肽(<=0.7 nmol/L;>0.7 nmol/L)进行随机化分层。

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

All participants will be centrally assigned to randomized study intervention using an interactive response technology (IRT).The randomization and intervention allocation are performed centrally by the IRT which generates the participant randomization list and allocates the intervention number and the corresponding intervention kits to the participants according to it.Randomization is stratified by age (<12 years; >=12 years), HbA1c (<8.5%; >=8.5%), and random C-peptide (<=0.7 nmol/L; >0.7 nmol/L), at screening.
