^aStrain-specific mean lifespan (days).

^bThe food intake (g/mouse/day) was measured on a weekly basis. The values are the average of food intake from 3–5 months to 12 months of age.

^cFertility (litter size) was measured in the generation of mice preceding the lifespan cohort and defined as the average litter size of the first three litters.

^dFertility (litter/female) defined as the average number of litters per strain.

^eThe sedative-hypnotic response to a high-dose, intraperitoneal injection of ethanol, defined as time to regain loss of righting reflex (LORR). The LORR data are from Bennett et al., 2006.

^fThe p values of the Pearson correlation coefficients (r) are all from 2-tailed tests.
