  2. Values are mean ± SD. 1 Unadjusted P value. Analyses were conducted using the MIXED procedure with SAS version 9.4. Vitamin C was log10 transformed. Significant P values are in bold. LSMEANS pairwise comparisons were performed when the main interaction factor effect was considered statistically significant (P < 0.05). Results that do not share the same letter (a, b) are significantly different (P < 0.05) from each other. BBP: n = 24 (week 0) and 23 (4 and 8 weeks); placebo: n = 22 (week 0) and 23 (4 and 8 weeks)
