aDays of shock, number of illness days prior to the first shock; GI, gastrointestinal; HCT, hematocrit; PLTs, platelets; WBC, white blood cell. Admission day, fever days prior to admission and day 1 of illness were assigned as the day of fever onset. bMedian (minimum, maximum) calculated using the Mann–Whitney U test for continuous variables not normally distributed. cMean ± SD calculated using Student’s t-test for continuous variables normally distributed.
