The average values of laboratory parameters and vital signs within 24 h of ICU admission were used in this study ( Hu et al, 2021 ; Zhang et al, 2021 ; Wang et al, 2022 ). We extracted the data related to comorbidities using the International Classification of Diseases (ICD)-9 or ICD-10 diagnosis codes.…”
