I eyeballed the actual number from Figure 1, which says that the numbers were taken from extrapolations from rodent data, which in context means from rodent CR data. I assume that this was a pretty rough, straightforward interspecies proportional extrapolation. A quick check based on reasonable assumptions appears to confirm this: the most common level of rodent CR is 40%, which yields a 40% increase in mean LS; the 1985 life expectancy data on which the whole figure is based pegged a woman of 50 yrs' life expectancy at 81 yrs; this would give 32.4 extra years of life.
