" our findings validate the predictive value of the abcd score in identifying hospitalized tia patients with a high risk of early stroke and provide further evidence for its potential applicability in clinical practice , " the authors conclude “我們的研究結(jié)果驗(yàn)證了abcd評(píng)分系統(tǒng)對(duì)住院tia患者早期中風(fēng)高風(fēng)險(xiǎn)的預(yù)測(cè)價(jià)值,并且提供更進(jìn)一步的證據(jù)表明其臨床應(yīng)用前景, ”作者總結(jié)道。

The predictive value of heart rate variability is independent of other noninvasive measures commonly used to predict prognosis of cardiac diseases , low left ventricular ejection fraction , and so on . like other risk predictors , measures of heart rate variability have modest positive predictive accuracy when used alone . however , combining measures of heart rate variability with other risk predictors yields a positive predictive accuracy of about 50 % 心率變異性的預(yù)測(cè)價(jià)值獨(dú)立于其他非創(chuàng)傷性預(yù)測(cè)心臟疾病預(yù)后指標(biāo)(降低的左心室射血分?jǐn)?shù),頻發(fā)重復(fù)性室性心律失常等) ,在單獨(dú)應(yīng)用時(shí)陽(yáng)性預(yù)報(bào)率較低,但與其他指標(biāo)聯(lián)合應(yīng)用,陽(yáng)性預(yù)報(bào)率可達(dá)50 。
Tail length , tail moment , tail dna percentage , and correction rate were compared between the improved software and the original one , and epidemiological indices for the improved software were also calculated and analyzed , including sensitivity , specificity , youden index , crude agreement , adjusted agreement , positive predictive value , negative predictive value , positive likelihood ratio , and negative likelihood ratio . results the improved software can correctly analyze most of the images to which the original one cannot give right results 比較改進(jìn)前后的尾長(zhǎng)、尾矩、尾dna百分含量上的差異、改進(jìn)前后分析正確率差異、以及改進(jìn)后的軟件以不同dna損傷級(jí)別為截?cái)嘀蹬卸?yáng)性結(jié)果的靈敏度、特異度、 youden指數(shù)、粗一致性、調(diào)整一致性、陽(yáng)性預(yù)測(cè)值、陰性預(yù)測(cè)值、陽(yáng)性似然比和陰性似然比。
