Comparison of changes in body weight induced by chitosan and placebo treatments.
| Placebo ∆ | Chitosan ∆ | p-Value Chitosan vs. Placebo | |
|---|---|---|---|
| All subjects (kg) | −3.35 ± 2.51 *** | −3.51 ± 3.64 *** | 0.7234 # |
| % subjects decrease | 90.9 | 88.5 | 0.7660 # |
| % subjects increase | 9.1 | 11.5 | |
| Change vs. baseline | |||
| Spearman R | −0.0918 | 0.3349 | |
| Spearman p-value | 0.5051 | 0.0083 | |
| Difference in slope (p-value ) | 0.1796 $ | 0.0157 $ | 0.0060 & |
∆ Wilcoxon p-value, expressing the significance of the change compared to zero, *** p < 0.001, # 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.
