Note. a 0 s in variables are excluded. # 0 s were NOT Excluded (Intubation Days)
b P-values are determined from median regression for Mannitol, Amount, and Epi; Poisson regression for Intubation days, and Log-Normal regression for other continuous variables. Extubation group (IE + EE vs. DE) was used as the main predictor adjusting for age, weight, and length as covariates.NAs are due to limited sample size. P < 0.05 are in bold character
