Linear regression and correlation analysis
Linear regression showed a significant effect of Impella® implantation
on in-hospital mortality (R2=0.15 , ANOVA p=0.01,
95%CI = -0.853 - -0.232) , ECMO weaning (R2=0.08 ,
ANOVA p=0.014, 95%CI = 0.092 – 0.805), and renal failure requiring
dialysis (R2=0.13 , ANOVA p=0.01, 95%CI =0.12 –
0.93). The need for red blood units was also significantly associated
with Impella® support (R2 =0.17, 16.132 95% CI 7.57
– 24.6, p =0.00). Data were presented in Table 4.
