Using linear regression, slopes, intercepts and R-squared of the relationship between duration of nursing bouts (x-axis) and final T_b at the end of nursing bouts (y-axis) were determined on individual mice. Litter size shows the number of offspring at weaning. Sample size (n) shows the number of nursing bouts recorded during lactation. Degrees of freedom (d.f.), F values for each individual are given in the table.

^*Indicates significance at the p < 0.05 level using the Holm-Bonferroni sequential adjustment for multiple testing.
