          摘  要  目的  对二甲双胍控制不佳的2型糖尿病(T2DM)患者使用卡格列净或司美格鲁肽治疗的长期经济性进行评价。方法
          从我国卫生体系角度出发,构建Markov模型,基于SUSTAIN 8研究数据模拟我国T2DM患者在二甲双胍基础上联用卡格列净或
          司美格鲁肽治疗30年的长期成本和效用,并以2024年我国人均国内生产总值(GDP)的1倍作为意愿支付(WTP)阈值计算增量成
          本-效果比(ICER)和增量净货币收益(INMB)。通过单因素敏感性分析、概率敏感性分析以及情境分析确认基础分析结论的稳定
          性。结果  与卡格列净+二甲双胍方案相比,司美格鲁肽+二甲双胍方案的ICER为260 485.67元/质量调整生命年(QALY),大于本
          研究设定的WTP阈值(95 749元/QALY),INMB为-61 576.24元,卡格列净+二甲双胍方案更具经济性优势。司美格鲁肽+二甲
          双胍方案组糖尿病无并发症治疗成本对INMB的影响最大,但参数在选定范围内的变动不会驱动结果发生逆转。随着WTP阈值
          的增加,司美格鲁肽+二甲双胍方案在经济性上的可接受概率呈上升趋势。在当前 WTP 阈值下,司美格鲁肽的年成本需下降
          42.95%,司美格鲁肽+二甲双胍方案才能成为更具经济性优势的方案。结论  从中国卫生体系角度出发,对于单用二甲双胍血糖
          控制不佳的T2DM患者,卡格列净+二甲双胍方案相较于司美格鲁肽+二甲双胍方案更具经济性优势。

          ABSTRACT   OBJECTIVE  To  evaluate  the  long-term  cost-effectiveness  of  canagliflozin  or  semaglutide  in  patients  with  type  2
          diabetes  mellitus(T2DM)poorly  controlled  with  metformin.  METHODS  Based  on  the  perspective  of  China’s  health  system,  a
          Markov  model  was  used  to  calculate  the  long-term  costs  and  utilities  of  canagliflozin  or  semaglutide  combined  with  metformin  for
          T2DM patients in China for 30 years based on the data from SUSTAIN 8 study. The incremental cost-effectiveness ratio(ICER) and
          incremental net monetary benefit (INMB) were calculated using one time the 2024 per capita gross domestic product(GDP) as the
          willingness-to-pay(WTP)  threshold.  One-way  sensitivity  analysis,  probability  sensitivity  analysis  and  scenario  analysis  were
          conducted  to  confirm  the  stability  of  the  conclusions.  RESULTS  Compared  with  canagliflozin  +  metformin,  ICER  of  semaglutide
          combined with metformin was 260 485.67 yuan/quality-adjusted life year (QALY),which was higher than the WTP threshold set in
          this study (95 749 yuan/QALY),and the corresponding INMB was -61 576.24 yuan,indicating that the canagliflozin + metformin
          regimen  was  more  cost-effective.  The  cost  of  diabetes  without  complications  treatment  in  the  semaglutide  +  metformin  group  had
          the  greatest  influence  on  INMB,but  changes  in  parameters  within  the  selected  range  did  not  drive  decision  reversal.  With  the
          increasing  of  WTP  threshold,the  economic  acceptability  of  semaglutide  +  metformin  regimen  increased.  Under  the  current  WTP
          threshold,the  annual  cost  of  semaglutide  should  be  reduced  by  42.95%  to  make  the  semaglutide  +  metformin  regimen  more  cost-
