Cox Regression Analysis of Factors Associated with Hospitalized Atrial Fibrillation

	P Value	Hazard Ratio	95% CI
Age > = 71 (vs. <48)	0.0002	9.96	2.98–33.28
Hemodialysis (vs. PD)	0.015	2.19	1.17–4.13
Digoxin use (1 = present, 0 = absent)	0.002	3.91	1.65–9.27
Pre-Dialysis SBP, mm Hg (vs. <130)
130–146	0.028	0.37	0.15–0.89
147–162	0.043	0.43	0.19–0.98

SBP = systolic blood pressure, PD = peritoneal dialysis, LVH = left ventricular hypertrophy
