  1. Upper-case letters in columns denote statistically significant differences (p < 0.05) between groups throughout least square means test. Lower-case letters in rows denote statistically significant differences (p < 0.05) between time points by analysis of variance for measurements repeated over time. * Osmolarity presented difference in the T0 h, thus those values were included as covariates in the statistical analyses of this variable
