Fig. 1. Pearson correlation analyses between brain-derived neurotrophic factor (BDNF) levels and Beck’s Depression Inventory (BDI) score changes among the 3 groups. X-axis represents BDI score changes and y-axis represents BDNF changes. As shown, there is negative correlation between the change in BDNF levels and BDI scores over 8-week supplementation period, while the correlation in probiotic group (r = –0.79, P < 0.001) is larger compared to prebiotic group (r = –0.19, P = 0.190) or placebo group (r = –0.69, P = 0.001).
