Comparison of serum klotho levels between two groups. A Comparison of serum klotho concentrations between normal controls and MHD patients. B, Comparison of serum klotho concentrations between males and females in normal controls. C, Comparison of serum klotho concentrations between males and females in MHD patients. D, Comparison of serum klotho concentrations between subjects with VC on abdominal aortic artery or other types of arteries in normal controls. E, Comparison of serum klotho concentrations between subjects with VC on abdominal aortic artery or other types of arteries in MHD patients. **** indicates P < 0.0001, * indicates P < 0.05. N = 140 per group for Fig. 1A; N = 50 for the male group and 90 for the female group in Fig. 1B; N = 53 for the male group and 87 for the female group in Fig. 1C; N = 8 for group of abdominal aortic artery and 13 for group of other arteries in Fig. 1D; N = 54 for group of abdominal aortic artery and 44 for group of other arteries in Fig. 1E.
