Cumulative incidence of treatment emergent assisted mechanical ventilation due to pulmonary injury for patients transfused with PRPC and CPC. (A) The cumulative incidence of TEAMV-PD in patients who received transfusion with ≥1 PC for the mITT data set (CPC, blue; PRPC-INTERCEPT), red). The hazard ratio (HR) and 95% CIs were estimated from the Cox proportional hazards regression for 1223 CPC patients and 1068 PRPC patients. The incidence of TEAMV-PD for PRPC recipients was 1.7% compared with 3.1% for CPC recipients (log rank P = .030; HR, 0.543; 95% CI, 0.310-0.951). (B) The cumulative incidence of TEAMV-PD in patients who received transfusion with ≥2 PCs for the mITT data set (CPC, blue; PRPC, red). The HR and 95% CIs were estimated from the Cox proportional hazards regression for 816 CPC patients and 773 PRPC patients. The incidence of TEAMV-PD for PRPC recipients was 2.2% compared with 4.4% for CPC recipients (log rank P = .016; HR, 0.498; 95% CI, 0.280-0.887).
