SIRT3 and Sepsis: Sirt3 had good negative correlations with SOFA scores both in sepsis and septic shock groups (Pearson: r2 = − 0.424, − 0.518; P = 0.011, 0.040), and Sirt3 correlated strongly with ScvO2 in the septic shock group (Pearson: r2 = − 0.679, P = 0.004) and with PCT in the sepsis group (Pearson: r2 = − 0.409, P = 0.015).
