Comparison of changes in BMI resulting from chitosan and placebo treatments.
| Placebo ∆ | Chitosan ∆ | p-Value Chitosan vs. Placebo | |
|---|---|---|---|
| All subjects (kg/m2) | −1.08 ± 0.89 *** | −0.95 ± 1.73 *** | 0.539 # |
| % subjects decrease | 81.8 | 80.3 | 1.000 # |
| % subjects increase | 18.2 | 19.7 | |
| Change vs. baseline | |||
| Spearman R | −0.2397 | −0.1505 | |
| Spearman p-value | 0.0780 | 0.2470 | |
| Difference in slope ( p-value) | 0.0781 $ | 0.1703 $ | 0.7124 & |
∆ 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.
