Comparison of changes in serum high density lipoprotein (HDL) cholesterol induced by chitosan and placebo treatments.
| Placebo ∆ | Chitosan ∆ | p-Value Chitosan vs. Placebo | |
|---|---|---|---|
| All subjects (mg/dL) | −1.06 ± 6.81 | −1.15 ± 7.65 | 0.8701 # |
| % subjects decrease | 55.6 | 52.5 | 0.8516 # |
| % subjects increase | 44.4 | 47.5 | |
| Change vs. baseline | |||
| Spearman R | −0.5054 | −0.1491 | |
| Spearman p-value | <0.0001 | 0.2513 | |
| Difference in slope (p-value) | 0.0004 $ | 0.1810 $ | 0.9648 & |
∆ Wilcoxon p-value expressing the significance of the change compared to zero, # data are expressed as p-values using the Mann–Whitney test, $ value expresses whether slope is different from zero, & value expresses whether slopes under chitosan and placebo treatments are different.
