The Relationship between PP and survival rate
Within 10 days after the ICUadmission, the PP group exhibited a notably higher survival rate compared to the non-PP group (78.2% vs64.1%, p=0.049) (Fig.4A). PP group demonstrated survival rates of 48.7% and 32.1% within 20 and 30 days, respectively (Fig.4B, C). Multiple PP cycles improved hospitalization survival: One time (81.0%, 17/21) vs Two times (82.6%, 19/23) vs Three times (100.0%, 15/15). Notably, there was no significant disparity in SOFA score based on the frequency of PP (Fig.4D, E).
