The prevalence of LVH, the concentration of BUN, Scr, iPTH and CRP, the level of LVMI, LVDd, IVST, PWT, SBP and DBP, and the prevalence of hypertension in CKD patients with IR were higher than those without IR; contrastively, eGFR and the concentrations of Hb and HDL in CKD patients with IR were lower than those without IR (P < 0.05, respectively, Table 3). Here, CRP is linked to chronic kidney disease.
