Figure 1From: Decreased expression of HLA-DR antigen-associated invariant chain mRNA predicts mortality after septic shockKaplan-Meier analysis of septic shock patients' 28-day survival after stratification on CD74 mRNA expression. The threshold was chosen based on the Youden index calculated on the receiver operating characteristic curve. There is a significant difference between the two curves (log-rank test, P < 0.001; hazard ratio = 7.065, 95% CI = 2.56 to 19.48)Back to article page
