Table 3:

Treatment category versus thromboembolic complication rate

Treatment CategorySymptomatic Thromboembolic Complication
No, n (Row %)Yes, n (Row %)Total N
Antiplatelet therapy (before and after)253 (98.1)5 (1.9)258
Antiplatelet therapy (after only)84 (97.7)2 (2.3)86

  • Note:X2 indicates likelihood ratio; P =.0133. The percentage of patients in the “before and after” group (1.9%) who had thromboembolic complications is very comparable with the percentage of patients in the “after only” group (2.3%).
