Table 2.

All-cause mortality in the subset of AFFRIM patients 70 to 80 years with atrial fibrillation

	Events (%)		Absolute risk difference^*	Hazard ratio (95% CI)	P value
	Rate-control strategy	Rhythm-control strategy	Absolute risk difference^*	Hazard ratio (95% CI)	P value
Pre-match (N=2248)	n=1118	n=1130
Randomized, subgroup of patients age 70-80 years	210 (19%)	252 (22%)	−3%	0.82 (0.69–0.99)	0.039
Additional multivariable- adjustment^a	---	---	---	0.80 (0.66–0.96)	0.018
Additional adjustment for propensity scores	---	---	---	0.83 (0.69–1.00)	0.048
Post-match (N=1874)	n=937	n=937
Propensity-matched	172 (18%)	215 (23%)	−5%	0.77 (0.63–0.94)	0.010

Absolute risk difference was calculated by subtracting the percentage of events in the rhythm control group from that in the rate control group.
