| 93 days | 93.8 ± 1.5 | 0.6 ± 0.1 | 5.2 ± 1.3 | 8.1 ± 1.2 |
| 125 days | 125.1 ± 0.6 | 3.5 ± 0.5 (P < 0.0001) | 25.2 ± 4.8 (P < 0.0001) | 7.3 ± 0.7 (P = 0.211) |
| 135 days | 135 ± 0 | 4.1 ± 0.5 (P < 0.0001) | 26.1 ± 4.4 (P < 0.0001) | 6.4 ± 0.6 (P = 0.001) |
| Neonatal | 5.3 ± 3.9 | 4.9 ± 1.2 (P < 0.0001) | 37.2 ± 8.6 (P < 0.0001) | 7.5 ± 0.7 (P = 0.447) |
Data are means ± SD. Statistical comparisons were made vs. 93 days, by 1-way ANOVA with Dunnett’s multiple comparison test. Number of animals: 93 days, n = 4; 125 days, n = 8; 135 days, n =11; neonatal, n =10.
