Comparisons of mechanically ventilated patients with good and poor short-term prognoses. a Seasonal distribution in the mechanically ventilated GBS patients with good short-term prognosis (Subgroup 1) was similar to that in the poor-short-term prognosis (Subgroup 2) (spring, 32.4 % versus 20 %; summer, 17.6 % versus 30 %; autumn, 20.6 % versus 30 %; winter, 29.4 % versus 20 %; all p > 0.05). b Time from onset to admission (3.5 versus 3.6, p > 0.05) and time from onset to nadir (5.8 versus 6.2, p > 0.05) were not significantly different. c MRC at nadir was significantly lower in the poor short-term prognosis group compared with the good short-term prognosis group (26.9 versus 7.4, p < 0.05). d As the infection complications during hospitalization were related to the prognosis of patients, we further compared the incidence of complications and found it was similar between two groups (85.3 % versus 92.5 %, p > 0.05).
