  2. ISS: Injury Severity Score; VATS: Video-Assisted Thoracoscopic Surgery; PCS: Physical component summary; MCS: Mental component summary.
  3. aMeasures general aspects of health; scores range from 0 to 100, with higher scores representing better well-being (§P < 0.01).
  4. Significant difference between ISS < 20 group and ISS ≥ 20 group (*P < 0.05; **P < 0.01); Significant difference between Sepsis group versus Non-Sepsis group (#P < 0.05; ##P < 0.01); Significant difference between MODS group versus Non-MODS group (&P < 0.05).
