Table 2. Unadjusted and multivariable-adjusted logistic regression analysis of the association of atrial fibrillation (AF) with ethnicity and geographic region, by sensitivity to detect AF*.

Method to Detect AF		Belt vs non-Belt OR (95%CI)	Black vs white OR (95% CI)
SR plus ECG	Model 1	0.80 (0.58–1.10)	0.19 (0.12–0.32)
	Model 2	0.69 (0.50–0.95)	0.20 (0.12–0.33)
	Model 3	0.66 (0.47–0.92)	0.20 (0.12–0.33)
ECG	Model 1	0.83 (0.65–1.06)	0.39 (0.29–0.52)
	Model 2	0.77 (0.60–0.98)	0.43 (0.31–0.57)
	Model 3	0.71 (0.55–0.92)	0.40 (0.29–0.54)
SR	Model 1	1.02 (0.91–1.14)	0.80 (0.71–0.90)
	Model 2	0.99 (0.88–1.10)	0.78 (0.70–0.88)
	Model 3	0.96 (0.85–1.08)	0.70 (0.62–0.79)
SR or ECG	Model 1	1.01 (0.91–1.12)	0.80 (0.71–0.89)
	Model 2	0.98 (0.88–1.09)	0.79 (0.70–0.88)
	Model 3	0.95 (0.85–1.06)	0.71 (0.63–0.80)

*Model 1 = unadjusted; model 2 = adjusted for age, sex, and ethnicity (in region analysis) or region (in ethnicity analysis); model 3 = adjusted for model 2 variables, plus hypertension, diabetes, and BMI.
