BMD is a prognostic factor for overall survival in critically ill patients. (A) ICU patients with a baseline BMD value < 152 HU have significantly impaired OS compared to patients with a BMD value above 152 HU. (B) Kaplan–Meier curve analysis reveals that OS is particularly poor in patients with BMD values below the 25th percentile. In these patients, median OS is only 3.29 weeks compared to 261.57 weeks in patients whose BMD upon ICU admission ranged within the upper quartile. (C) When applying the optimal prognostic cut-off value of 122 HU, Kaplan–Meier curve analysis shows significantly shorter OS in patients with a BMD value < 122 HU compared to patients with a BMD value above this cut-off value.
