**Figure 1.** Association between basal metabolic rate (BMR) (**A, B**), basal fat oxidation (BFox) (**C, D**) and basal carbohydrate oxidation (BCHox) (**E, F**) with plasma S-klotho levels. I� (unstandardized regression coefficient), R^{2}, and P are from simple linear regression analysis. Abbreviations: BMR_{LM}; Basal Metabolic Rate relative to lean mass.
