The study population was subdivided into patients with hyperuricemia and with normal uric acid levels. Hyperuricemia was defined as uric acid level exceeding 6 mg/dl for men or 5 mg/dl for women. The difference between men and women in the prevalence of uricemia is highly significant (p < 0.001, based on Pearson‘s test) despite the fact that the cutoff for men was higher than for women.
