highly significantP = 0.008
Compared to the null model (which included only the intercept term, assigning all patients the same baseline risk of 23.2%), the 24-week GPR model demonstrated highly significant reclassification improvement.: continuous NRI = 0.972 (95% CI: 0.000–1.160, P = 0.008), categorical NRI = 0.486 (95% CI: 0.259–0.711, P < 0.001), IDI = 0.024 (95% CI: 0.010–0.040, P = 0.002).
