Prognostic Value of the Charlson Comorbidity Index for Mortality and Machine Learning-Based Prediction in Critically Ill Patients with Paralytic Ileus: Retrospective Cohort Study.

When CCI was the ordinal variable, patients in higher quartiles of CCI were significantly associated with a higher risk of in-hospital death compared with participants in the lowest quartile in all 3 established Cox regression analysis models: unadjusted model (HR 3.124, 95% CI 1.945‐5.017; P <.001), partially adjusted model (HR 2.950, 95% CI 1.708‐5.097; P <.001), and fully adjusted model (HR 2.447, 95% CI 1.210‐4.951; P =.01) and showed an increasing trend with increasing CCI ( Table 3 and Figure 3A ).
