Data are presented as the median (Med), minimum (min), maximum (max) and relative frequency (Freq) in percentage (%) of spontaneous behaviour by group and time (T) −96, 24 and 48 hours. Superscript case (x): significant difference when −96 h is compared to 24 h; At each time point, different letters (higher case (a) or (b)) indicate significantly different values among treatment groups. Significant differences are presented in bold. Bonferroni-corrected alpha level was of 0.0041.
