Results of hazard ratios comparing atrial high-rate events variables for each clinical outcome based on Cox regression model

Clinical outcome	AHRE variable
	Low AHRE vs. zero AHRE	High AHRE vs. zero AHRE	High AHRE vs. low AHRE
TE	HR 4.3	HR 9.4	HR 2.4
	(CI 0.73–26.2)	(CI 1.8–47.0)	CI (0.58–9.8)
	P= 0.11	P= 0.006	P= 0.23
TE + cardiovascular death	HR 2.1	HR 4.0	HR 2.0
	(CI 0.72–6.0)	(CI 1.5–10.1)	(CI 0.73- 5.6)
	P= 0.17	P= 0.004	P= 0.18
TE + AFa+ HFb+ cardiovascular death	HR 1.0	HR 3.8	HR 3.9
	(CI 0.49–2.1)	(CI 2.3–6.3)	(CI 1.9–7.9)
	P= 1.0	P< 0.0001	P< 0.0001

Low AHRE corresponds to a burden of 14 min to <3.8 h in 24 h monitoring period, high AHRE corresponds to a burden >3.8 h in a 24 h monitoring period.
