KL and metabolic syndrome: Table 3 demonstrates the correlation between the Klotho protein concentration and metabolic syndrome components. In the adjusted model, the Klotho protein concentration inversely correlated with the number of metabolic syndrome components (3: p < 0.001 and 4–5: p = 0.002). In statistical analysis of each component, Klotho protein concentrations were inversely correlated with abdominal obesity (p < 0.001) and high TG (p < 0.001). A positive correlation was noted between Klotho protein concentration and high glucose. (p = 0.002).
