Figure 1.

Six-panel figure presenting the relationship between logLDAR and patient outcomes. Panels A to C show hazard ratio plots for ICU and in-hospital mortality with MIMIC-IV and external data, each displaying red lines for hazard ratio, shaded confidence intervals, and P values for non-linearity. Panels D to F show Kaplan-Meier survival curves categorized by LDAR tertiles (low, medium, high) for ICU and in-hospital survival, with survival probability on the y-axis and time in days on the x-axis, all indicating statistically significant differences by tertile.

Dose-response relationship and Kaplan-Meier survival curves for logLDAR and short-term mortality. (A–C) Restricted cubic spline plots for 28-day ICU mortality (internal cohort), in-hospital mortality (internal cohort), and ICU mortality (external cohort), adjusted for Model 2 covariates. (D–F) Kaplan-Meier curves stratified by logLDAR tertiles for ICU survival (internal), in-hospital survival (internal), and ICU survival (external). Log-rank P-values are shown.
