Derivatization of Free Natural Glycans for Incorporation onto Glycan Arrays: Derivatizing Glycans on the Microscale for Microarray and Other Applicati

free glycans while maintaining the closed?ring structure. After purification of the labeled glycans, they can be printed on a glass surface to create a natural glycan microarray, suitable for interrogation with potential glycan?binding proteins

预测值

特异度=d/（b＋d）=84/91=92％ 　　假阳性率=b/（b＋d）=7/91=8％ 　　患病率=（α＋c）（α＋b＋c＋d）=104/195=53％ 　　阳性预测值=α/（α＋b）=55/62=89％ 　　阴性预测值=d/（c＋d）=84/133=63％ 　　该作者在结论中说：“阳性结果在预测存在显著的冠状动脉狭窄的男人中是有用的，但阴性结果并不能用来排除显著的冠状动脉狭窄。” 　　上述例子的患病率为53％，在患病率低
