Demographics and clinical characteristics categorized according to the final diagnosis. NIHSS, National Institutes of Health Stroke Scale; tPA, tissue plasminogen activator; LKN, last known normal. Bold indicates a significant p value. *Fisher’s exact value could not be calculated, therefore Chi-square values were reported.
