Results of the linear mixed-effects model assessing the effect of treatment, age, litter size, and sex on “PC 2—Whimpering”. The p-value for litter refers to the ANOVA comparing the models with and without litter included. “Bonferroni-corrected α for treatment” indicates the alpha level (after sequential Bonferroni correction) to determine whether the treatment effect was significant.
