did not reach statistical significanceP = 0.0631
In the segment after the threshold, the association shifted in a positive direction but did not reach statistical significance (β = 0.19, 95% CI: -0.01, 0.39, P = 0.0631).
In the segment after the threshold, the association shifted in a positive direction but did not reach statistical significance (β = 0.19, 95% CI: -0.01, 0.39, P = 0.0631).
A significant trend across quartiles was observed in all models (all P for trend < 0.0001), indicating a robust and consistent inverse association between PIV and Klotho levels.
