测量指标:

Outcomes:

指标中文名:

进行减重治疗的患者Week 12、Week 24达到 DLQI 6分以下 [皮肤病生活质量指数(Dermatology Life Quality Index, DLQI)]的患者占比。

指标类型:

次要指标

Outcome:

Proportion of patients undergoing weight loss treatment who achieve a Dermatology Life Quality Index (DLQI) score below 6 at Week 12 and Week 24.

Type:

Secondary indicator

测量时间点:

12,24周

测量方法:

DLQI(皮肤病生活质量指数) 是一份简单、患者自评的、包含10个项目的、经过验证的生活质量问卷。评分范围为0至30分,分数越高表示生活质量受损越严重。

Measure time point of outcome:

Week,12,24

Measure method:

The DLQI is a simple, patient-reported, 10-item, validated, quality of life questionnaire. Scores range from 0 to 30, with higher scores indicating greater impairment of quality of life.

指标中文名:

进行减重治疗的患者Week 12、Week 24 体重较基线变化

指标类型:

次要指标

Outcome:

Changes from baseline in body weight at Week 12 and Week 24 in patients undergoing weight loss treatment

Type:

Secondary indicator

测量时间点:

12,24周

测量方法:

用体重秤测量

Measure time point of outcome:

Week,12,24

Measure method:

Measured with a scale

指标中文名:

进行减重治疗的患者Week 12、Week 24达到PGA0/1[银屑病静态临床医生整体评估(Physician’s Global Assessment, PGA)]的患者占比

指标类型:

次要指标

Outcome:

Proportion of patients undergoing weight loss treatment who achieve a Physician’s Global Assessment (PGA) score of 0 or 1 at Week 12 and Week 24.

Type:

Secondary indicator

测量时间点:

12,24周

测量方法:

PGA(静态临床医生整体评估) 是由研究者执行的一项多项目量表。它用于在特定时间点,整体评估参与者的银屑病皮损。整体皮损根据斑块肥厚、鳞屑和红斑的程度进行分级,评分范围为:清除(0)、基本清除(1)、轻度(2)、中度(3)、重度(4)。

Measure time point of outcome:

Week,12,24

Measure method:

The PGA is an investigator-administered multi-item scale. It determines the participant's psoriasis (PsO) lesions, overall, at a given time point. Overall lesions are graded for plaque elevation, scaling, and erythema, on a range of clear (0), almost clear (1), mild (2), moderate (3), and severe (4).

指标中文名:

达到PASI 3分以下 [银屑病皮损面积和严重程度指数(Psoriasis Area and Severity Index,PASI)]的患者占比

指标类型:

主要指标

Outcome:

Proportion of patients undergoing weight loss treatment who achieve a Psoriasis Area and Severity Index (PASI) score below 3

Type:

Primary indicator

测量时间点:

24周

测量方法:

PASI评分是用于评估银屑病严重程度和范围的一种工具(银屑病面积与严重程度指数)。评估时,需为身体的每个区域选择一个具有代表性的皮损区域。对银屑病的红斑、肥厚和鳞屑的严重程度进行评估,等级分为无(0)、轻度(1)、中度(2)、重度(3)或极重度(4)。将四个身体区域的这三项强度评分分别相加,得到小计分数 A1, A2, A3, A4。 每个小计分数需乘以该区域代表的体表面积比例。 ? A1 ×

Measure time point of outcome:

Week 24

Measure method:

A PASI score is a tool used to measure the severity and extent of psoriasis (Psoriasis Area and Severity Index). A representative area of psoriasis is selected for each body region. The intensity of redness, thickness and scaling of the psoriasis is assessed as none (0), mild (1), moderate (2), severe (3) or very severe (4). The three intensity scores are added up for each of the four body regions to give subtotals A1, A2, A3, A4. Each subtotal is multiplied by the body surface area represented

本研究采用纸质CRF表进行数据收集、储存和交互。从电子病历系统采集患者信息,包括姓名缩写、性别、年龄、身高、体重、腹围、臀围、银屑病出现时间、既往史、家族史、目前应用药物、治疗反应、过敏史、皮损拍照、用胶带粘取银屑病皮损及正常皮肤表面、受累体表面积(Body Surface Area, BSA)、银屑病皮损面积和严重程度指数(Psoriasis Area and Severity Index,PASI)、银屑病静态临床医生整体评估(Physician’s Global Assessment, PGA)、皮肤病生活质量指数(Dermatology Life Quality Index, DLQI)等信息。所有采集的信息完成数据录入和核查后,按编号的顺序归档保存,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:

This study utilizes paper-based Case Report Forms (CRFs) for data collection, storage, and exchange. Patient information is extracted from the electronic medical record system, including initials, gender, age, height, weight, waist circumference, hip circumference, time since psoriasis onset, past medical history, family history, current medications, treatment response, allergy history, photographs of skin lesions, tape strip samples from lesional and normal skin surfaces, involved Body Surface Area (BSA), Psoriasis Area and Severity Index (PASI), Physician's Global Assessment (PGA), Dermatology Life Quality Index (DLQI), and other relevant information. All collected information, after data entry and verification, is archived sequentially by identification number for future reference. Electronic data files, including databases, review programs, analysis programs, and analysis results, should be categorized and stored with multiple backups saved on different disks or recording media to ensure proper preservation and prevent damage. All original archives must be retained for the duration specified in the relevant regulations.
