随机方法(请说明由何人用什么方法产生随机序列):

本试验采用分层区组随机化方法,以临床试验机构(中心)及创面病种(烧伤,压力性损伤,糖尿病足)为分层因素。采用SAS 9.4(或以上版本)统计软件,给定种子数和区组长度,按1:1的比例将受试者随机分为A组和B组,产生至少60例受试者的随机分组表。

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

This trial uses a stratified regional group randomization method with the clinical trial site (center) as the stratification factor. Using SAS 9.4 (or higher) statistical software, subjects are randomized into groups A and B in a 1:1 ratio given the seed number and length of the block group, generating a randomized group table of at least 60 subjects.
