ED: Emergency Department. Dichotomic variables are represented as n (%). Age, time from symptom onset and blood test results are presented as median and interquartile range (in brackets). P-value was calculated with Pearson’s χ2 test for dichotomic variables and with Mann-Whitney U-test for continuous variables.
