Abstract
ObjectiveTo validate the significance of iScore, PLAN score and ASTRAL score in predicting the outcome of Chinese patients at 3 month after acute ischemic cerebral stroke (AIS). Methods: From December 2012 to August 2013, 221 AIS patients who hospitalized in neurology department of our hospital were collected prospectively. Related baseline data were recorded and calculated by iScore, PLAN score and ASTRAL score. The outcome events were defined as death and poor functional outcome, or modified Rankin Scale (≥3). Model discrimination was quantified by calculating the area under the Receiver Operating Characteristic curve (AUC), and calibration was assessed by goodness of fit test and correlation coefficient. Results: Seventy-one cases (32.1%) had 3-month an unfavorable outcome. AUC for iScore, PLAN score and ASTRAL score were 0.816, 0.830 and 0.841 respectively.x2 of were 1.676, 5.976 and 12.858 (all >0.05), and correlation coefficient were 0.899, 0.857 and 0.939 (all <0.05), respectively. Conclu-sion: All the three scales can predict 3-month functional outcomes in Chinese stroke patients precisely and reliably. There was a high correlation between observed and expected probability of unfavorable outcome.关键词
