随机方法(请说明由何人用什么方法产生随机序列):

使用SPSS制作随机分组表,根据随机分组表顺序,分配到数字“0”的患者在左腹部采用1565nm非剥脱点阵激光,右腹部采用1064nm超皮秒点阵激光;分配到数字“1”的患者在左腹部采用1064nm超皮秒点阵激光,右腹部采用1565nm非剥脱点阵激光。

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

Use SPSS to create a random grouping table. According to the order of the random grouping table, patients assigned to the number "0" will receive a 1565nm non-ablative fractional laser on the left abdomen and a 1064nm ultra-picosecond fractional laser on the right abdomen; patients assigned to the number "1" will receive a 1064nm ultra-picosecond fractional laser on the left abdomen and a 1565nm non-ablative fractional laser on the right abdomen.

数据采集和管理(说明:数据采集和管理由两部分组成,一为病例记录表(Case Record Form, CRF),二为电子采集和管理系统(Electronic Data Capture, EDC),如ResMan即为一种基于互联网的EDC:

1.数据收集录入: 主要通过电子文档形式录入患者基本信息(姓名、年龄、性别)、病例信息(主诉、现病史、既往史、诊断)、用相机记录患者皮损情况,并以电子照片形式保存患者信息。研究者根据受试者的原始观察记录,将数据及时、完整、正确、清晰地载入患者对应的病例报告。经过监察员审核、签字后的调查表应及时送交临床研究数据管理员。 录入采用相应的数据库系统双人双机录入,之后对数据库进行两遍比对,期间若发现问题及时通知研究者,要求研究者做出回答。他们之间的各种疑问及解答的交换应当采用疑问表形式,疑问表应保存备查。 2.数据核查和管理 当所有病例报告表经双份输入并核对无误后,由数据管理员写出数据库检查报告,其内容包括研究完成情况(含脱落受试者清单)、入选/排除标准检查、完整性检查、逻辑一致性检查等。在审核会议上,由主要研究者、申办单位代表、监查员、数据管理员和统计人员对受试者签署知情同意书、数据库检查报告中提出的问题做出决议,写出审核报告,数据库同时将被锁定。 3.数据存档 病例报告在按要求完成数据录入和核查后,按编号的顺序归档保存,并填有检索目录等,以备查考。电子数据文件包括数据库、检查程序、分析程序、分析结果、编码本和说明文件等,应分类保存,并有多个备份保存于不同磁盘或记录介质上,妥善保存,防止损坏。所有原始档案应按相应规定内的期限保存。

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

1. Data collection and entry: In the process of small sample verification and formal verification, the collected patient information is properly stored. The patient's basic information (name, age, gender), case information (chief complaint, present history, past history, diagnosis), the patient's skin lesions were recorded with cameras. Patient information is stored in the form of electronic photographs. According to the original observation records of the subjects, the data will be timely, complete, correct and clear into the patient's corresponding case report. The questionnaire, which has been reviewed and signed by the ombudsman, should be sent to the clinical study data Manager in a timely manner. The corresponding database system was used for two-person and two-machine input, and then the database was compared twice. During the period, if any problem was found, the researcher was promptly notified and asked to answer. The exchange of questions and answers between them shall be in the form of a question table, which shall be kept for future reference. 2. Data verification and management After all the case report forms are entered and verified correctly, the data manager writes the database inspection report, which includes the study completion status (including the list of dropped subjects), the inclusion/exclusion criteria check, the integrity check, the logical consistency check, etc. At the audit meeting, the main researcher, the representative of the bidding unit, the supervisor, the data administrator and the statistician will make a decision on the informed consent signed by the subjects and the problems raised in the database inspection report, write the audit report, and the database will be locked. 3. Data archive After data entry and verification are completed as required, case reports shall be archived and stored in numbered order and filled with search directories for reference. Electronic data files, including databases, inspection programs, analysis programs, analysis results, coding and explanatory files, should be classified and stored in different disks or recording media with multiple backups, properly stored to prevent damage. All original files shall be kept for the period specified accordingly.
