When serum Klotho < 9.746 per 100 pg/mL, the risk of anemia was reduced by 10.9%, and this reduction was significant (P<0.001); however, when Klotho > 9.746 per 100 pg/mL, this relationship was not significant (\documentclass[12pt]{minimal}\usepackage{amsmath}\usepackage{wasysym}\usepackage{amsfonts}\usepackage{amssymb}\usepackage{amsbsy}\usepackage{mathrsfs}\usepackage{upgreek}\setlength{\oddsidemargin}{-69pt}\begin{document}$$P = 0.298$$\end{document}P=0.298). Here, KL is linked to anemia.
