Correlation between age and metabolic syndrome for AI patients and control participants.

<p>(A) The correlation of age with the number of fulfilled metabolic syndrome criteria was investigated by Spearman's rank correlation analysis for AI patients and controls. Significant correlation was found only for controls (Spearman's rank correlation coefficient r_s = 0.363, ***<i>P</i><0.000). (B) The prevalence of the metabolic syndrome in AI patients and control participants in different age groups is given (≤34 years old AI patients: n = 22; ≤34 years old control participants: n = 36; 35 to 44 years old AI patients: n = 27, 35 to 44 years old control participants: n = 23; ≥45 years old AI patients: n = 31; ≥45 years old control participants: n = 41). Significance of differences was assessed by the Chi-square test (*<i>P</i><0.05, ***<i>P</i><0.001).
