Body mass in C57BL/6 × 129 mice of very old age
| Age | Female (g)a | Male (g) |
|---|---|---|
| 24 (mo) | 29.4 ± 6.3 | 35.2 ± 6.1 |
| 27 (mo) | 26.8 ± 2.1 | 32.4 ± 3.0 |
| 30 (mo) | 25.4 ± 6.3 | 29.4 ± 5.0 |
Data analyzed by a mixed linear model with animal as a random effect (age × sex × animal) at 24, 27, and 30 months of age (mo; n = 5 for males and females in each age group); main effect of sex (p = .01), no effect of age (p = .12), or their interaction (p = .91). Data shown as mean ± SD.
