Incidence of recurrent AF after catheter ablation according to CRP quartiles

Variable	CRP level				P trend
	Quartile 1	Quartile 2	Quartile 3	Quartile 4
Quartile value, mg/l	< 0.8	0.8–1.4	1.5–2.7	> 2.7
Events/Patients	60/201	61/171	55/167	71/172
Incidence, %a	33.1	41.9	37.0	53.4	0.017
95% CI	24.4–42.3	32.1–54.7	29.9–49.1	41.6–68.5

P value was calculated by trend test of survival function across quartiles
