The bars show significant differences in cumulative incidences of hypertension from prehypertension between the subjects with and without hyperuricemia by χ2 analyses.
A) Normal blood pressure
The cumulative incidence of hypertension over five years and the numbers of subjects (n) were 5.6% (n=783) in total with hyperuricemia, 2.6% (n=6,104) in total without hyperuricemia, 6.9% (n=189) in women with hyperuricemia, 2.2% (n=4,141) in women without hyperuricemia, 5.2% (n=594) in men with hyperuricemia, and 3.3% (n=1,963) in men without hyperuricemia.
B) Prehypertension
The cumulative incidence of hypertension over five years and the numbers of subjects (n) were 30.7% (n=726) in total with hyperuricemia, 24.0% (n=2,858) in total without hyperuricemia, 38.2% (n=131) in women with hyperuricemia, 23.1% (n=1,372) in women without hyperuricemia, 29.1% (n=595) in men with hyperuricemia, and 24.8% (n=1,486) in men without hyperuricemia.
