Figure 1.

Effects of CP2305 intake on time-dependent changes in questionnaire and visual analog scores. Time-dependent changes in scores of STAI trait anxiety (a) and PSQI global score (b) in the CP2305 and placebo groups are shown. In addition, the visual analog scales were used to assess stressful irritability (c) and abdominal discomfort (d). The black circles represent CP2305 and the white represent the placebo groups. Data are presented as the mean ± SEM. The p values and partial eta squared values are shown in each panel; these were determined by repeated-measures ANOVA between the groups without multiple comparison correction. Asterisks indicate overall significance between the groups across time points. * p < 0.05.
