Figure 4H illustrated that the calibration curve results validated the remarkable precision of the nomogram model in predicting patient outcomes for ARDS. As shown in Figures 4I, J, the levels of CX3CR1, PID1 and PTGDS gene expression were found to be lower in the ARDS group induced by sepsis compared to both the sepsis-only and control groups. Here, CX3CR1 is linked to Sepsis.
