Prevalence of CHADS2 variables in patients with and without thrombus
| No Thrombus N = 596 (%) | Thrombus N = 46 (%) | P value | Odds Ratio | 90% Confidence Interval | |
|---|---|---|---|---|---|
| CHADS2 Score | 1.7 ± 1.2 | 2.4 ± 1.2 | 0.0005 | 1.528 | 1.203 – 1.940 |
| CHF | 270 (45.2) | 46 (100) | <0.0001 | * | |

No odds ratio as all thrombus patients had CHF.
CHF = congestive heart failure; TIA = transient ischemic attack.
