患者ID（Patient ID）*

请填写患者ID Please enter patient ID

患者姓名（Patient Name）*

请填写患者姓名 Please enter patient name

性别（Gender）*

请选择性别 Please select gender

年龄（Age，岁/y）*

请输入有效年龄（18-120岁）Please enter valid age (18-120 years)

1. 手术次数（Surgery Count）*

请输入有效次数（≥0的整数）Please enter valid number (integer ≥0)

评分规则：0次=0分，1次=1分，≥2次=3分（OR=2.08，风险因素）| Scoring Rule: 0 points for 0 times, 1 point for 1 time, 3 points for ≥2 times (OR=2.08, Risk Factor)

指标定义：患者既往接受的内瘘相关手术次数（含首次造瘘手术）
Definition: Number of previous fistula-related surgeries (including initial fistula creation)
临床意义：多次手术通过机械创伤和炎症反应促进新生内膜增生，形成"血管损伤累积"效应，显著升高狭窄风险
Clinical Significance: Multiple surgeries promote neointimal hyperplasia through mechanical trauma and inflammatory responses, forming "vascular injury accumulation" and significantly increasing stricture risk
统计依据：每增加1次手术，狭窄风险升高2.08倍（95%CI:1.52-2.84，p<0.0001）
Statistical Basis: Each additional surgery increases stricture risk by 2.08 times (95%CI:1.52-2.84, p<0.0001)

2. 血栓病史（Thrombosis History）*

请选择是否有血栓病史 Please select thrombosis history

评分规则：有=1分，无=0分（OR=1.96，风险因素）| Scoring Rule: 1 point for yes, 0 points for no (OR=1.96, Risk Factor)

查看详细说明 | View Detailed Explanation

指标定义：患者既往是否发生过与AVF相关的血栓形成事件（经超声或血管造影证实）
Definition: Whether the patient has a history of AVF-related thrombosis (confirmed by ultrasound or angiography)
临床意义：血栓病史与狭窄风险密切相关，反映血管内皮功能损伤和凝血状态异常
Clinical Significance: Thrombosis history is closely associated with stricture risk, reflecting vascular endothelial injury and abnormal coagulation
统计依据：有血栓病史患者的狭窄风险是无血栓病史患者的1.96倍（95%CI:1.08-3.57，p=0.0266）
Statistical Basis: Patients with thrombosis history have 1.96 times higher stricture risk than those without (95%CI:1.08-3.57, p=0.0266)

3. 术后1年未手术（No Surgery First Year）*

请选择是否术后1年未手术 Please select no surgery within first year

评分规则：是=2分，否=0分（OR=0.42，保护因素）| Scoring Rule: 2 points for yes, 0 points for no (OR=0.42, Protective Factor)

查看详细说明 | View Detailed Explanation

指标定义：AVF首次造瘘术后1年内，未因狭窄、血栓等并发症接受任何手术干预
Definition: No surgical intervention for complications such as stricture or thrombosis within 1 year after initial AVF creation
临床意义：术后1年无手术史表明内瘘成熟良好，血管生物学特性优异，长期预后更佳
Clinical Significance: No surgery within 1 year indicates well-matured fistula with favorable vascular biology and better long-term prognosis
统计依据：术后1年未手术患者的狭窄风险降低58.5%（95%CI:0.28-0.63，p<0.0001）
Statistical Basis: Patients with no surgery within 1 year have 58.5% lower stricture risk (95%CI:0.28-0.63, p<0.0001)

4. 血红蛋白浓度（Hemoglobin，g/L）*

请输入有效浓度（60-150g/L）Please enter valid concentration (60-150g/L)

评分规则：≤90g/L=0分，>90g/L=1分（OR=1.01，风险因素）| Scoring Rule: 0 points for ≤90g/L, 1 point for >90g/L (OR=1.01, Risk Factor)

查看详细说明 | View Detailed Explanation

指标定义：空腹静脉血检测的血红蛋白浓度（常规实验室检测指标）
Definition: Fasting venous blood hemoglobin concentration (routine laboratory indicator)
临床意义：血红蛋白升高可增加血液粘稠度，改变血流动力学，通过调节HIF-1α表达参与狭窄发病机制
Clinical Significance: Elevated hemoglobin increases blood viscosity, alters hemodynamics, and participates in stricture pathogenesis by regulating HIF-1α expression
统计依据：血红蛋白每升高1g/L，狭窄风险升高1.01倍（95%CI:1.00-1.02，p=0.0049）
Statistical Basis: Each 1g/L increase in hemoglobin increases stricture risk by 1.01 times (95%CI:1.00-1.02, p=0.0049)
