Table 4.

Arrhythmia incidence and 95% confidence interval (CI) for the difference in proportions between the control and dexmedetomidine (DEX) groups after propensity score matching

	Control (n = 468)	DEX (n = 468)	p-Value^*	Proportion Difference (95% CI)^†
One or More Arrhythmia	41% (194)	46% (213)	0.22	0.05 (−0.02 – 0.10)
Tachyarrhythmia (TA)	31% (144)	29% (137)	0.66	−0.02 (−0.07 – 0.04)
TA Receiving Intervention	17% (81)	14% (65)	0.16	−0.03 (−0.08 – 0.01)
Bradyarrhythmia (BA)	15% (72)	18% (82)	0.44	0.03 (−0.03 – 0.07)
BA Receiving Intervention	9% (41)	12% (55)	0.17	0.03 (−0.01 – 0.07)
