Serum concentration of IFN-γ, IL-1β and IL-12 before and after the 8-week Chlorella supplementation. Mean ± SE, tested by paired t-test (intra group comparison) or independent t-test (intergroup comparison). There were no significant differences in the baseline values between the Chlorella group and the placebo group. ^*P <0.05, ^**P <0.01 compared with the value at baseline in each group; ^ϕP <0.01, ^ϕϕP <0.001, comparison of Δ change value between the Chlorella group and the placebo group.
