Table 2.

Association of hyperuricaemia with all-cause mortality and heart failure hospitalization, before and after propensity-score matching

	Events (%)		Absolute risk difference (%)^a	Hazard ratio (95% confidence interval)	P-value
	Normal uric acid^b	High uric acid^c	Absolute risk difference (%)^a	Hazard ratio (95% confidence interval)	P-value
Before matching	n = 1223	n = 1422
All-cause mortality	312 (26%)	530 (37%)	+11	1.65 (1.44–1.90)	<0.001
Heart failure hospitalization	390 (32%)	634 (45%)	+13	1.68 (1.48–1.91)	<0.001

After matching	n = 630	n = 630
All-cause mortality	179 (28%)	209 (33%)	+5	1.44 (1.12–1.85)	0.005
Heart failure hospitalization	220 (35%)	264 (42%)	+7	1.27 (1.02–1.58)	0.031

^aAbsolute differences in event rates were calculated by subtracting the event rates in the high uric acid group from the event rates in the normal uric acid group (before values were rounded).

^bNormal uric acid is defined as serum uric acid of ≤6 mg/dL for women and ≤8 mg/dL for men.

^cHigh uric acid is defined as serum uric acid of >6 mg/dL for women and >8 mg/dL for men.
