| Day 30 | 5.17 ± 0.75 | 4.97 ± 0.72 |
| Day 60 | 4.94 ± 0.701 | 5.16 ± 0.82 |
| Triacylglycerol, TAG (mmol/L) | ||
| Day 1 | 1.09 ± 0.69 | 1.15 ± 0.61 |
| Day 30 | 1.14 ± 0.61 | 1.06 ± 0.54 |

1Although time × treatment interaction was significant, p = 0.001 (2-factor repeated measures ANOVA) and TC was significantly lower for OPP compared to control treatment (at day 60), based on Wilcoxon signed rank test (p = 0.025), no significant difference of total cholesterol level was found between OPP and control treatments at day 1, 30 and 60 following Bonferroni correction.
2Baseline HDL-C level was significantly different between treatments, p = 0.038 (Wilcoxon signed rank test). The value was further used as covariate in repeated measures. Although the time × treatment analysis was significant, p = 0.011 (2-factor repeated measures ANOVA), no significant difference of HDL-C level was found between treatments at day 30 and 60 based on Wilcoxon signed rank test. Similarly, no significant difference of HDL-C level was found between treatments at day 30 and 60 after Bonferroni correction.
3Although the time × treatment interaction was significant, p = 0.018 (2-factor repeated measures ANOVA) and LDL-C was significantly lower for OPP compared to control treatment (at day 60) based on Wilcoxon signed rank test (p = 0.04), no significant difference of LDL-C level was found between OPP and control treatments at day 1, 30 and 60 following Bonferroni correction.
