To compare Greek stroke score with available previous two stroke scores for the diagnosis of cerebral ischemia and hemorrhage in acute stroke patients, and validate the Greek stroke score.
A tertiary hospital in India.
In a prospective study acute stroke patients were evaluated with Greek stroke score, Allen score and Siriraj stroke score. Comparability (Kappa Statistics) and validity (sensitivity, specificity, negative predictive value and positive predictive value) of the Greek stroke score and previous scores were tested.
Out of the 91 patients enrolled in the study, 47 patients had cerebral infarction and 44 patients had hemorrhage by CT scan. Allen score was uncertain/equivocal in 39 patients, Siriraj Stroke score in 22 and Greek stroke score in 47 patients. Sensitivity, Specificity, positive predictive value, negative predictive value for Allen score were 0.5(95% CI:0.34,0.58), 0.94(95% CI:0.86,0.98), 0.81(95% CI:0.56,0.95), 0.78(95% CI: 0.71,0.81) for Siriraj score were 0.75(95% CI: 0.63,0.84), 0.81(95% CI: 0.71,0.89), 0.77(95% CI: 0.65,0.86), 0.78(95% CI 0.69,0.86) and for Greek Score were 0.42(95% CI: 0.23,0.53), 0.93(95% CI: 0.87,0.98), 0.71(95% CI:0.39,0.91), 0.81(95% CI:0.75,0.85) respectively. Greek stroke score was compared with previous scores using kappa statistics which revealed substantial strength of agreement between the Allen Score for certain results.
The overall comparability of Greek stroke score and Allen score was better as compared to Greek stroke score and Siriraj stroke score. Greek Stroke score was more specific in diagnosing hemorrhage as compared to Siriraj score. However, all these stroke scores lack accuracy hence could not be applied safely to guide the physician in management of stroke.
比较希腊卒中评分与之前两种可用的卒中评分，用于诊断急性卒中患者的脑缺血和脑出血，并验证希腊卒中评分。
印度一家三级医院。
在一项前瞻性研究中，对急性卒中患者进行希腊卒中评分、艾伦评分和诗里拉杰卒中评分评估。测试希腊卒中评分与之前评分的可比性（kappa统计量）和有效性（敏感性、特异性、阴性预测值和阳性预测值）。
在该研究纳入的91例患者中，47例经CT扫描诊断为脑梗死，44例为脑出血。艾伦评分在39例患者中不确定/模棱两可，诗里拉杰卒中评分在22例患者中不确定/模棱两可，希腊卒中评分在47例患者中不确定/模棱两可。艾伦评分的敏感性、特异性、阳性预测值、阴性预测值分别为0.5（95%CI：0.34,0.58）、0.94（95%CI：0.86,0.98）、0.81（95%CI：0.56,0.95）、0.78（95%CI：0.71,0.81）；诗里拉杰评分的敏感性、特异性、阳性预测值、阴性预测值分别为0.75（95%CI：0.63,0.84）、0.81（95%CI：0.71,0.89）、0.77（95%CI：0.65,0.86）、0.78（95%CI：0.69,0.86）；希腊评分的敏感性、特异性、阳性预测值、阴性预测值分别为0.42（95%CI：0.23,0.53）、0.93（95%CI：0.87,0.98）、0.71（95%CI：0.39,0.91）、0.81（95%CI：0.75,0.85）。使用kappa统计量将希腊卒中评分与之前的评分进行比较，结果显示在某些结果方面，艾伦评分之间存在高度一致性。
与希腊卒中评分和诗里拉杰卒中评分相比，希腊卒中评分与艾伦评分的总体可比性更好。与诗里拉杰评分相比，希腊卒中评分在诊断脑出血方面更具特异性。然而，所有这些卒中评分都缺乏准确性，因此不能安全地应用于指导医生管理卒中。
