Performance of machine‐learning approach for prediction of pre‐eclampsia in a middle‐income country
ABSTRACT Objective Pre‐eclampsia (PE) is a serious complication of pregnancy associated with maternal and fetal morbidity and mortality. As current prediction models have limitations and may not be applicable in resource‐limited settings, we aimed to develop a machine‐learning (ML) algorithm that offers a potential solution for developing accurate and ...

尿沉渣UF-100检查中鉴别女性尿路感染与尿液污染指标参数的探讨
目的通过对临床尿路感染组和尿液标本污染组患者尿沉渣和干化学结果对比分析,寻找鉴别尿常规标本是尿路感染或者白带污染的指标参数。方法用受试者工作特征曲线(receiver operating characteristic curve,ROC)分别对尿沉渣结果中白细胞(WBC)、上皮细胞数(EC)、上皮细胞/白细胞比值(E/W)进行评价并计算曲线下面积。结果 WBC、EC、E/W的ROC曲线下面积分别为0.209,0.746,0.976,E/W比值的曲线下面积最大,其最优截断点约为0.22,诊断的灵敏度为0 ...
