3.3 Associations between baseline glucose indices and risk of
CKD
Figure 2 shows the incidence of CKD in quartiles of the different
baseline glucose indices. The incidence of CKD tended to increase with
increasing FPG, 2h OGTT, HbA1c, fasting insulin, and HOMA-IR (all, P for
trend < 0.001). No differences of CKD were found in HOMA-β
quartiles (P=0.734). HOMA-IR exhibited the strongest correlations with
increased risk of CKD in all of the Cox regression analysis models
(Table 3). The HR for the risk of CKD in the first (lowest) quartile of
HOMA-IR was 1.00 (reference); for the second quartile the HR=1.15 (95 %
CI: 0.79-1.69); for the third quartile the HR=1.22 (95% CI: 0.84-1.78);
and for the fourth quartile (highest) the HR=1.61 (95% CI: 1.10-2.34).
