Figure 6.
Nest-building scores did not differ significantly between phlebotomy groups. A modified version of a published nest-scoring system9 was used to score nests built within a 4-h period. Mice were moved to a clean cage with a new cotton square about 6 h after phlebotomy and removed from the cage 4 h later for euthanasia. Pictures of the nests then were scored by an assessor who was blind to phlebotomy group. (A) Examples of nests receiving each indicated score. (B) Quantification of average nest score by group. The FV group seemed to exhibit a lower average nest score, but the difference was not significant (Kruskal–Wallis test: H4,42 = 3.519, P = 0.475). Error bars represent SEM.
