Women: baseline characteristics and the onset of impaired fasting glucose* according to uric acid levels.

Values are expressed as mean ± standard deviation.

Quartile 1: uric acid <220 (µM); quartile 2: uric acid 220–249.9 µM; quartile 3: uric acid 250–279.6 µM; quartile 4: uric acid >279.6 µM.

For continuous values, differences among groups were assessed using one-way analysis of variance. The chi-square test was employed for comparisons of prevalence. The Cochran–Armitage test was used to assess the trend in the incidence rates of impaired fasting glucose onset according to the uric acid groups.

*Onset of impaired fasting glucose was defined as a fasting plasma glucose level ≥6.11 mM.
