If tests for normality or equal variance failed, results are for ANOVA on ranks. Groups are intact, decentralized, P [low], PC [low], PCR [low], P [mid], PC [mid], PCR [mid], wash. p values smaller than α are printed in bold. N, number of animals; df, degrees of freedom; res, residual. Note that despite the significant effect from ANOVA, the pairwise comparison for PY on phase did not show any significant differences between groups (Fig. 3B).
