[摘 要] 目的:比较 MELD 3. 0、MELD⁃Na和MELD 评分对肝硬化失代偿期患者3个月和1年生存预后的预测效能。方法:
回顾性收集2013年1月—2022年12月合肥市第一人民医院门诊及住院的肝硬化失代偿期438例患者的临床资料,分别根据
随访3个月及1年的生存状态分为生存组和死亡组,利用受试者工作特征(receiver operating characteristic,ROC)曲线)以及曲
线下面积(area under the curve,AUC)、校准曲线、净重分类改善度(net reclassification improvement,NRI)、综合区分改善度(inte⁃
grated discrimination improvement,IDI)和决策曲线(decision curve analysis,DCA)比较 MELD 3. 0、MELD⁃Na 和 MELD 评分的预
测价值。结果:438例患者随访3个月和1年的病死率分别为15.53%和26.26%。MELD 3. 0、MELD⁃Na 和MELD评分预测3个
月病死率的 AUC 值分别为 0.859(0.805~0.913)、0.857(0.802~0.912)和 0.856(0.800~0.911);预测 1 年病死率的 AUC 值分别为
0.841(0.796~0.886)、0.832(0.785~0.880)和 0.830(0.782~0.878),各组间差异均无统计学意义(P 均>0.05)。3 种评分在所有患
者的分布中,MELD 3.0评分能将18.0%的MELD⁃Na 评分患者的评分区间上调,21.5%的MELD评分患者被重新归类为较高区
间的评分。在校准曲线上,3 种评分在时间点上的预测概率和实际概率方面展现出相似的趋势。在预测 3 个月病死率上,
MELD 3. 0较MELD的NRI为0.240(0.009~0.401,P=0.032);在预测1年病死率方面,MELD 3.0相比MELD的NRI和IDI分别为
0.201(0.079~0.401)、0.032(0.006~0.057),差异均有统计学意义(P < 0.05)。亚组分析显示 3 种评分在不同性别、病因及 Child
分级患者中差异均无统计学意义(P > 0.05)。结论:MELD 3.0评分在NRI、IDI方面显著优于传统模型,展现出更好的风险分层
能力,为肝硬化失代偿患者的临床预后评估提供更可靠的决策依据。

[Abstract] Objective:Comparison of the predictive performance of MELD 3.0,MELD⁃Na,and MELD scores in assessing the 3⁃
month and 1⁃year survival prognosis of patients with decompensated cirrhosis. Methods:We conducted a retrospective analysis of
clinical data from 438 patients diagnosed with decompensated cirrhosis who received either outpatient or inpatient care from January
2013 to December 2022. Based on their survival status at 3 months and 1 year,the patients were categorized into survival and death
groups. The predictive value of MELD 3.0,MELD⁃Na,and MELD scores for 3⁃month and 1⁃year mortality was compared using receiver
operating characteristic(ROC)curves,the area under the curve(AUC),calibration curves,net reclassification improvement(NRI),
integrated discrimination improvement(IDI),and decision curve analysis(DCA). Results:At the 3⁃month and 1⁃year follow⁃up points,
15.53% and 26.26% of patients had died,respectively. The area under the curve(AUC)for predicting 3⁃month and 1⁃year mortality for
the MELD 3.0,MELD⁃Na,and MELD scores were 0.859(0.805-0.913),0.857(0.802-0.912),0.856(0.800-0.911)and 0.841(0.796-
0.886),0.832(0.785-0.880),0.830(0.782-0.878),respectively. However,the differences were not statistically significant(P > 0.05).
In the distribution analysis across all patients,MELD 3.0 score can increase the score range for 18.0% of patients with MELD⁃Na
