Note. CMC = carboxymethylcellulose. Lab analyses were done only on the per-protocol analysis sample (n = 189). All comparisons between groups were accomplished using ANOVA (baseline period) or ANCOVA (supplement period).There was no significant difference among groups for any values in the baseline period.

In baseline period, M (mean) (SD [standard deviation]), in supplement period, M adjusted for baseline values (SEM).

p < .001 and

p = .002 for among group comparisons in the supplement period. Pairwise comparisons were adjusted for multiple comparisons using Tukey’s LSD.

For pairwise comparisons, values that do not share a letter within a row differ significantly, p < .05.
