In-hospital death at 7 d | 7.2 | 8.3 | 5.2 | 7.4 | 0.5 |
In-hospital death at 30 d | 13.3 | 15.1 | 10.8 | 13.6 | 0.4 |

Length of stay, d, mean ± SE | 15.7 ± 1.3 | 16.7 ± 4.7 | 15.7 ± 2.5 | 16 ± 1.6 | < 1.0 |
Note: SE = standard error. *Unless otherwise stated †Test of proportions among 3 groups; length of stay was assessed by analysis of variance. The only difference between groups was seen on hemorrhagic transformation because no hemorrhages occurred in one group with a very small sample.
