Multivariable analysis for AF detection in the high-risk group
| Variables | OR (95 % CI) | P-value |
|---|---|---|
| Congestive heart failure (yes) | 0.85 (0.31–2.33) | |
| Hypertension (yes) | 0.97 (0.70–1.36) | |
| Diabetes mellitus (yes) | 0.65 (0.37–1.15) | |
| Prior stroke/TIA (yes) | 0.83 (0.59–1.16) | |
| Vascular disease (yes) | 0.52 (0.27–0.99) | 0.047 |
| Gender (female) | 0.53 (0.38–0.74) | <0.001 |
| BMI (kg/m2) | 1.05 (1.01–1.10) | 0.011 |
| Log NT-proBNP | 3.06 (2.39–3.75) | <0.001 |
The low-risk group was not included in the multivariable analysis, as they only performed an index-ECG and there was no further attempt to diagnose AF.
AF, atrial fibrillation; BMI, body mass index; CI, confidence interval; ECG, electrocardiogram; NT-proBNP, N-terminal B-type natriuretic peptide; OR, odds ratio; TIA, transient ischaemic attack.
