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.
