Different DTN distributions between with/without CBC before tPA.

<p>DTN = door to needle intervals, CBC = complete blood count, tPA = tissue plasminogen activator; INI = Illinois Neurological Institute/OSF Comprehensive stroke center.</p

The Comparison on door to needle intervals more of > 60 minutes in logistic regression model analysis.

<p>According to the door to needle (DTN) intervals of > 60 minutes or not, the patients were divided into two groups and related factors were assessed. Since DTN is a more accurate measure and the onset to treatment (OTT) intervals along with the ethnicity of patients were quite different from these two hospitals, we removed race and OTT from this analysis. OR = odds ratio; CI = confidential interval; NIHSS = National Institute of Health Stroke Scale; sICH = symptomatic intracranial hemorrhage; mRS = modified Rankin Scale were divided into two groups, favorable outcome as mRS scores 0 or 1, unfavorable outcome as mRS scores 2 or more; HS = Huashan Hospital; CBC = the complete blood counts result back before tPA.</p><p>The Comparison on door to needle intervals more of > 60 minutes in logistic regression model analysis.</p
