Table 1.
Chlorella intake did not significantly increase defecation frequency or blood folate levels.
| Effect sizea | p-valueb | C1c | T1c | C3c | T3c | |
|---|---|---|---|---|---|---|
| Defecation frequencyd (/week) | 0.101 (−0.426 to 0.628) | 0.702 | 3.95 ± 1.05 | 4.15 ± 1.42 | 4.98 ± 1.36 | 5.30 ± 1.99 |
| Blood folate level (ng/ml) | 0.208 (−0.604 to 1.020) | 0.607 | 9.21 ± 4.29 | 8.48 ± 3.39 | 8.10 ± 3.76 | 7.84 ± 2.95 |
a
Values are given as the mean and 95% confidence interval.
b
Values indicate paired t-test result.
c
Values are given as mean ± standard deviation (S.D.).
d
Values represent the mean defecation frequency per week, which was recorded for 2 weeks; C1 and T1 were recorded before the start of the placebo and test intervention periods, respectively. C3 and T3 were recorded during the 3rd and 4th weeks of each intervention period.
