^aNeto Angéloco et al. (2012, Table 3). The value given here is the mean value for a control group of Wistar rats given a “standard AIN-93 diet.”

^bReed et al. (2007, Section 2.4). The value given here is the overall mean for female mice from 40 strains.

^cBorrud et al. (2010, Table 3). The value given here is a weighted average of the mean values listed for females of “all races and ethnicities” for the age categories 8–11, 12–15, 16–19, and 20–39 years. Means for these age categories were converted to a weighted average by multiplying each mean by the sample size for the corresponding age category and then dividing by the sum of the sample sizes.

^dNicholas and Hartmann (1991, Table 2). The value given here is the average of the mean values listed for all 5 time points and for both diets.

^eJohnson et al. (2001). The value given here is the average for milk from 10 female mice (MF1) on day 15 of lactation.

^fArcus-Arth et al. (2005, Table 2). The value given here is the mean value for “all measurement periods” (through 12 months post-partum).
