Reason for non-thrombolysis. Multivariate analysis of reasons for non-thrombolysis divided by onset-to-admission delay (≤180 min vs >180 min)
| Patients (n=2019) | ≤180 min (n=659) | >180 min (n=1360) | OR | p Value | 95% CI |
|---|---|---|---|---|---|
| Too mild stroke | 323 (49%) | 567 (42%) | 3.35* | 0.000 | 1.82 to 6.18 |
| Age >80 years | 112 (17%) | 164 (12%) | 2.98* | 0.007 | 1.36 to 6.56 |
| Other bleeding reasons | 15 (2%) | 9 (1%) | 10.12* | 0.026 | 1.33 to 77.23 |
| Recent stroke (clinically or radiologically) <3 months | 36 (6%) | 13 (1%) | 4.50 | 0.071 | 0.88 to 23.01 |
| Other reasons | 16 (2%) | 8 (1%) | 13.77* | 0.033 | 1.23 to 153.68 |
| Microangiopathic stroke mechanism | 75 (11%) | 233 (17%) | 0.28* | 0.010 | 0.11 to 0.74 |
| Other determined or rare stroke mechanism | 54 (8%) | 32 (2%) | 3.48 | 0.096 | 0.80 to 15.08 |
| Atrial fibrillation | 179 (27%) | 287 (21%) | 1.94* | 0.034 | 1.05 to 3.58 |
| Mechanical or biological heart valves | 23 (4%) | 40 (3%) | 3.62* | 0.049 | 1.01 to 13.01 |
OR >1 means more likely ≤180 min and <1 means more likely >180 min.
