  1. MFGM, milk fat globule membrane; ANOVA, analysis of variance.
  2. Values are means ± SEM of 16 (placebo group [women, n = 7; men, n = 9]) and 19 (MFGM group [women, n = 11; men, n = 8]) subjects for RMS and 12 (placebo group [women, n = 5; men, n = 7]) and 16 (MFGM group [women, n = 10; men, n = 6]) subjects for MFCV, respectively.
  3. aThe value is the percentage change from the baseline to 10 weeks. Repeated-measures ANOVA for the group-by-time interaction (G × T) during the interventional period. bThere was a significant difference from the baseline during the interventional period, as determined using the Bonferroni test (P < 0.05). cThere was a significant difference between the two groups in results of the unpaired t-test (P < 0.05). dThere was a significant difference from the baseline to 10 weeks in results of the paired t-test (P < 0.05).
