Values are expressed as median (interquartile range [IQR]) and mean ± standard deviation. Lowercase letters indicate the difference (p < 0.05) among the groups at each collection time (Shapiro-Wilk followed by t test or Mann-Whitney). Upper case letters indicate difference (p < 0.05) among collection times for each group (Repeated measures ANOVA, followed by the Tukey-Kramer test)
