  • a n = 18 for M and HPLC diets; n = 16 for HPMC diet.

  • b Analyzed as one-way ANOVA with subject as random effect and diet as fixed effect. Standard error of the difference (SED) is based on 16 versus 18 observations. Diet means were compared by Tukey's test; different superscript capital letters within columns indicate P < 0.05.

  • c Analyzed with Friedman nonparametric ANOVA (no post hoc comparisons performed).
