Body weight
Changes in body weight over the 24-week intervention
period for the chitosan and placebo groups are shown in
Figure 2. In the last observation carried forward (LOCF)
analysis for the ITT population, the chitosan group lost a
mean (s.e.) of 0.39 (0.21) kg (0.4%) during the 24-week
period vs a net gain of 0.17 (0.16) kg (0.2%) for the placebo
group during the 24-week intervention. The mean (95%
confidence interval (CI)) difference between treatment
groups was therefore 0.56 (0.04, 1.08) kg (P ¼ 0.03, Table 2)
