Table 3 Incidence per 100,000 person years (p-yrs) at risk for developing incident gout in men and women by different levels of SU at baseline screening

From: The risk of clinically diagnosed gout by serum urate levels: results from 30 years follow-up of the Malmö Preventive Project cohort in southern Sweden

No of individuals by sex and s-UA SU at baseline (μmol/L) Incident gout (n) Person-years at risk Incidence (95% CI) per 100,000 person-years at risk Absolute risk (%)*

  1. *Mean follow-up (SD) for men 29.9 (8.7); 29.3 (8.9); and 27.9 (9.4); and for women 27.5 (7.3); 24.2 (7.5); and 23.5 (8.1) years
  2. *SU levels were missing in two men and one woman, which explains the difference in number of incident gout
