Results are presented in β coefficient and R

^{2}value of steady multivariate linear model after stepwise regression. R^{2}values are shown for each dependent variable (bold text, only variables with R^{2}are shown) and overall model (regular text). In β coefficient: Positive sign (‘+’) suggests increase in variable is associated with mortality; negative sign (‘−’) suggests decrease is associated with mortality.Significance level: *p<0.05, **p<0.01, ***p<0.001.

BE, base excess; CRRT, continuous renal replacement therapy; FiO

_{2}, fraction of inspired oxygen; NA, not available (due to limited number of subjects); NE, norepinephrine; NS, not significant (results); PPHN, persistent pulmonary hypertension of the newborn;
