Comparison of markers of endothelial function between patients with and those without progression of organ failure in the first week.

CAC = circulating angiogenic cell, EPC = endothelial progenitor cell; EMP = endothelial microparticle; PBMC = peripheral blood mononuclear cells; RHI = reactive hyperaemia index, SAPS = Simplified Acute Physiology; SOFA = Sequential of Organ Failure Assessment.Data presented as mean ± SEM or as number (percentage).*n = number of patients analysed with progression and no progression of organ failure respectively.CAC即循环血管生成细胞（circulating angiogenic cell），EPC为内皮祖细胞（endothelial progenitor cell）；EMP为内皮微粒（endothelial microparticle）；PBMC为外周血单个核细胞（peripheral blood mononuclear cells）；RHI为反应性充血指数（reactive hyperaemia index），SAPS为简化急性生理学评分（Simplified Acute Physiology）；SOFA为序贯器官衰竭评估（Sequential of Organ Failure Assessment）。数据以均值±标准误（standard error of the mean, SEM）或例数（百分比）的形式呈现。*n分别为发生器官功能恶化与未发生器官功能恶化的分析患者例数。
