Figure 1 Smoothed curve from the fully adjusted linear model with restricted cubic splines.
The shaded band indicates 95%CIs. The vertical line marks the estimated inflection (approximately 14.7 ng/mL). The outcome was modeled as FT3/FT4 × 100 for numerical scaling; inference is unaffected. 25(OH)D: 25-hydroxyvitamin D.
