3.1 Clinical characteristics of the study population
The 5,273 subjects had a mean age at baseline of 58.7 ± 7.2 years, and
after a mean follow-up interval of 3.6 ± 0.7 years, 335 (6.4%) had
developed new CKD. The clinical and biochemical characteristics of the
subjects at baseline are summarized in Table 1. Compared to those who
did not develop CKD, subjects that did had increased FPG, 2h OGTT,
HbA1c, fasting insulin, and HOMA-IR (all, P < 0.001).
However, HOMA-β was not different between the 2 groups.
