(A) A threshold, a non-linear association between the serum vitamin B12 (pg/mL) and serum α-Klotho (pg/mL) levels was observed in the unadjusted model (A,C) (p < 0.001, 0.0023) and adjusted model (B,D) (p < 0.001, <0.001), in a generalized additive model. In graphs (A,B), the red and blue lines represent the smoothed curve fits between the variables and their 95% confidence intervals, respectively.
