Notes: fPatients were grouped by quartile absolute count (0, 0.05×109/L, 0.17×109/L) of blood eosinophils and divided into group 1, 2, 3 and 4 (from low to high).IQR, interquartile range: 25%–75%; *Fisher’s exact probability method; **Mean (SD, standard deviation).
Abbreviations: N, number; E%, percent of blood eosinophil in white blood cell; E, absolute count of peripheral blood eosinophil; ICU, intensive care unit; NIMV, noninvasive mechanical ventilation; IMV, invasive mechanical ventilation.
