Results of ELISA for AGEs and sRAGE in the quartile intervals groups. Data are mean ± SE. AGEs, advanced glycation end products. sRAGE, soluble receptor of AGEs. HOMA-IR, homeostatic model assessment-insulin resistance. TT, total testosterone. FAI, free androgen index. a and b represent the levels of serum AGEs and sRAGE in the four HOMA-IR groups. H1 (HOMA-IR <2.49, n = 37), H2 (2.49 ≤ HOMA-IR < 3.92, n = 37), H2 (3.92 ≤ HOMA-IR < 5.88, n = 37), H4 (HOMA-IR ≥ 5.88, n = 37). P value for analysis of variance for differences between groups: * < 0.05 compared with H1, ** < 0.01 compared with H1. c and d represent the levels of serum AGEs and sRAGE in the four TT groups. T1 (TT < 1.22 nmol/L, n = 37), T2 (1.22 nmol/L ≤ TT < 2.09 nmol/L, n = 37), T3 (2.09 nmol/L ≤ TT < 2.69 nmol/L, n = 37), T4 (TT ≥ 2.69 nmol/L, n = 37). e and f represent the levels of serum AGEs and sRAGE in the four FAI groups. F1 (FAI < 3.41, n = 37), F2 (3.41 ≤ FAI < 6.73, n = 37), F3 (6.73 ≤ FAI < 10.59, n = 37), F4 (FAI ≥ 10.59, n = 37). P value for analysis of variance for differences between groups: * < 0.05 compared with F1. # < 0.05 compared with F2
