Notably, while the increase in C-index for the BAR-based model did not reach statistical significance when compared with the albumin-based model [ΔC-index: 0.004 (−0.001 to 0.009), p = 0.14], the BAR-based model yielded a significant improvement in risk reclassification, as evidenced by a positive continuous NRI of 0.138 (95% CI: 0.063–0.213).
