研究目的: |
开展人体随机对照干预试验,研究摄入不同剂量Lc19(对照组,低剂量组(1.0×10^10 CFU)和高剂量组(6.0×10^10 CFU) 菌株后的定植情况、肠道菌群变化及代谢组学变化。 |

随机方法(请说明由何人用什么方法产生随机序列): |
由未参与受试者招募与干预实施的第三方统计人员,采用 SPSS 软件生成的随机数字表法,按 1:1:1 的比例将受试者随机分配至对照组、低剂量组和高剂量组。随机序列由第三方保管,对研究者和受试者设盲。 |
||||||||
|
Randomization Procedure (please state who generates the random number sequence and by what method): |
A random number sequence will be generated by an independent statistician not involved in participant recruitment or intervention implementation, using the random number table method in SPSS software. Subjects will be randomly assigned to the control group, low-dose group, and high-dose group in a 1:1:1 ratio. The randomization list will be kept by the third party, with blinding maintained for both researchers and participants. |
