Table 4 Incidence per 100,000 person-years at risk and hazard ratios (HRs) for developing incident gout in men and women by different levels of urate at baseline healthcare screening. Results are presented separately for the two time periods; (a) baseline screening until 1998; and (b) from 1998 to end of study period

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
