Dataset of clinical characteristics and 90-day mortality in ICU sepsis patients

This dataset contains de-identified clinical data of 123 patients with sepsis admitted to the intensive care unit (ICU) between 2015 and 2018. Variables include demographic data (age, sex, BMI), disease severity scores (SOFA, APACHE II, NUTRIC), body composition measurements from abdominal CT (SMA, SMI, SMD, SAT), biomarkers (PCT), and clinical outcomes such as 90-day survival status and Charlson Comorbidity Index (CCI).

Variable definitions:
- Survival_Status: 1 = survived at 90 days, 2 = deceased
- Sex: 1 = male, 2 = female
- SMD_HU: Skeletal Muscle Density in Hounsfield Units
- SMA_cm2 / SAT_cm2: area in square centimeters

This dataset supports the findings of the manuscript titled “Risk factors analysis of 90-day mortality in patients with sepsis in intensive care unit” submitted to PLOS ONE.
